There are many different types of refrigerators and one of the most popular ones is stainless steel. This type of metal is highly durable and has a shiny finish. However, it is also highly susceptible to fingerprints and scratches.

The problem with using magnets on stainless steel fridge is that most of them have raised surfaces or sharp corners which can scratch the surface when you place magnets, remove, or drag them across the door. The best way to avoid this is to choose refrigerator magnets that do not have these characteristics and are made from vinyl.

Some stainless steel with fingerprint resistance features is not safe from magnets. They tend to ruin the surface by scratching. Dishwasher: Stainless steel dishwashers also cannot hold magnets. However, the newly designed ones are supportive. Those stainless steel dishwashers are thin and have a ferromagnetic underneath. It allows magnets to hold. Again, one should not use magnets on fingerprint-resistant stainless steel on the dishwasher as they will damage the surface.

Magnets can leave gray scuff marks on raised edges of the stainless steel surface. However, these marks usually are only on the outside and don’t penetrate the metal.

However, we strongly advise not to use magnets on Black Stainless or Fingerprint Resistant Stainless doors because the magnet can damage the finish.

Why Do Magnets Stick to Stainless Steel?

Whether or not a magnet sticks to stainless steel depends on the grain structure of the metal. Ferritic and Marternsitic stainless steels are magnetic, while austenitic stainless steels, which contain nickel, are not. The presence of iron in the stainless steel sheet can determine its magnetism as well.

Most 2017 and newer Stainless Steel refrigerators will hold a magnet. For older models or for models not addressed below, we recommend testing the refrigerator with a magnet to see if it will hold.

Do magnets stick to black stainless steel? In certain cases, yes. Magnets will stick to black stainless steel if the steel at its core is ferromagnetic. Whether or not magnets stick to black stainless steel also depends on whether the coating of the finish is thin enough to allow a magnet to cling to it.

How to Clean Stainless Steel With Magnets

If you have some fridge magnets still on your stainless steel fridge and notice gray scuff marks on the door, there are a few things that you can do to get rid of them. First, you need to find a stainless steel cleaner that isn’t harsh and is designed for this purpose.

After applying this cleaner, use a damp cloth to wipe away the scuffs. You may need to repeat the process several times until the scuffs fade away.

If you’re having trouble removing a deeper scratch, you may need to sand it out with a piece of fine wet/dry sandpaper. This will require a bit of elbow grease but is worth it for the results you can achieve.

How do you magnetize a refrigerator door

How to Magnetize a Refrigerator Door

If your refrigerator door is not sealing properly, the air inside the refrigerator door lightly your freezer can escape, making your food thaw and increasing your energy bill. One way to remedy this problem is to magnetize your fridge door.

Remagnetize Your Refrigerator Seal

Before you start this project, you should know that most refrigerator doors and freezer doors are made of a flexible gasket. This type of gasket features a long, flexible magnet embedded in it that creates a tight seal between the refrigerator’s main body and the door.

This flexible magnet is not as strong as neodymium magnets, but it’s much longer and covers a larger area than the neodymium magnets used in a lot of appliances.

Running a Neodymium Magnet over the Rubber Seal

The best and safest way to remagnetize a refrigerator or freezer door seal is to run a neodymium magnet over it. This will rejuvenate the magnet’s magnetic ability and re-activate its snugging function.

How Do You Check for Resistance?

To test the magnetic strength of vinyl magnets on your refrigerator’s or freezer’s seal, place a piece of paper between the door and the seal. Close the door, then remove the paper without opening the freezer.

If there is any resistance to removing fridge magnets scratch the paper, it means that the refrigerator’s or freezer’s seal has some weak points in the magnets. You may need to work on these points or replace the seal altogether.

Is 316 Grade Stainless Steel Magnetic?

In some instances, 316 grade stainless steel may be considered to be magnetic, but it depends on the specific alloy. The answer to this question largely depends on the amount of chromium and other elements that are present.

Corrosion Resistance: 316 stainless steels are known for their corrosion resistance, especially pitting corrosion which is highly localized and occurs when solutions containing chloride ions come in contact with the metal. These alloys also contain molybdenum which further improves the corrosion resistance of the metal.

316Ti: The 316Ti variant of 316 stainless steel contains a small amount of titanium. The titanium stabilizes the structure of 316 at high temperatures and prevents carbide precipitation at grain boundaries. This is beneficial for a variety of applications, including the manufacturing of valves and fittings that are subject to thermal stress at higher temperatures.

Alloying Elements: The 316 alloys contain the traditional chromium, nickel, and molybdenum in addition to other alloying elements that affect the overall properties of the material. The chromium content enhances the corrosion resistance of the alloy and the addition of nickel and molybdenum strengthens it.

Niobium (Columbium): Similarly to titanium, niobium is a stabilizer that lessens the formation of carbide precipitates at grain boundaries. Moreover, it helps to reduce the reactivity of the chromium.

While the 316 alloys are austenitic, as the metal cools they undergo a phase transition from austenite to martensite. The addition of nickel stabilizes the austenite against this change in microstructure, resulting in relatively low levels of magnetism in most cases.

How Can I Tell If My Stainless Steel Is 304 Or 316?

304 is the most commonly ordered stainless steel grade because of its ability to resist corrosion, oxidation and abrasion. It also offers great formability, strength and machinability making it a top choice in CNC machining and sheet metal fabrication.

316 is more expensive on the front end but can offer a longer functional lifespan for many stainless steel applications. It’s worth the extra cost if you need a higher level of resistance to chlorides, salts and acids in your application.

If you’re not sure which grade of stainless steel is right for your project, let us help you make the best decision possible! We are a full-line stainless steel supplier and service center with a national footprint.

Type 304: This is the most popular grade of stainless steel, known as “18/8” due to its high nickel and chromium content. It is a common choice for many applications and industries because it offers the basic corrosion resistance that stainless steel is known for at a more affordable price.

This grade of stainless is primarily made from iron and contains 8-10.5 percent nickel, 18-20 percent chromium, and a small amount of carbon, manganese, silicon and molybdenum. It’s the added molybdenum that makes this type of stainless steel more resistant to corrosion than other types of stainless.

304 is a good choice for most stainless steel projects, but it’s important to consider the specific environmental conditions that you plan on using your product in. You’ll want to choose a grade that will work best in the environment and keep you from having to replace the stainless steel prematurely.

How do you remove magnet residue from stainless steel appliances

How Do You Remove Magnet Residue From Stainless Steel Appliances?

A lot of people have stainless-steel refrigerators in their homes, and like many other home appliances they often become a place to store dust, dirt and magnets. As a result, they can be prone to fingerprints and other blemishes.

Fortunately, these stains can be easily removed. The trick is to use the right products and procedures.

The first step is to determine which type of stainless steel your appliance is made from. Some, different grades of of stainless are more rust-resistant than others, so make sure you choose one with the appropriate protection against corrosion.

Next, clean your stainless-steel appliances using a mild dish soap and warm water only. Rinse off the soap after each cleaning to avoid streaking.

Once you’re finished, wipe the surface dry with a clean rag. You may also want to add a little mineral oil or baby oil for an extra polish.

Another effective way to remove magnet residue is with a Magic Eraser, a product that’s easy to find at your local grocery store. This will help to remove magnet marks, lift the stains and leave your appliances looking sparkling.

Alternatively, you can try a stainless-steel scratch removal compound or even whitening toothpaste. These are both gentle enough to use on the brushed finish of stainless steel, but they’re still abrasive enough to buff out scratches without harming the stainless steel itself.

Keep in mind that all stainless steel can rust, so be careful when you’re scrubbing or using any cleaners that contain bleach, alcohol, ammonia, or chlorides. The abrasives in these cleaners can damage the chromium film that protects your stainless-steel appliances.

How do you hang things on a non magnetic refrigerator

How Do You Hang Things on a Non Magnetic Refrigerator?

If you’re wondering how do you hang things on a non magnetic stainless steel refrigerator well, you have come to the right place. In today’s post we will show you a variety of ways to display your notes, reminders and grocery lists on your stainless steel refrigerator without having to resort to a magnet board or hooks.

Cookie Sheet Magnetic Board

Use a cookie sheet that has been painted or decorated to your liking and stick it onto the fridge door with strong double sided tape. This is the perfect way to store recipes that you’ve been wanting to try, a calendar and a few important reminders.

Framed Sheet Metal

Another option for hanging your stuff is to cut a piece of sheet metal to fit the front of your pantry door or refrigerator. You need to find a metal sheet that is not made from aluminum and you’ll have to choose one of the smaller sizes available at your local hardware or hobby store.


If you have cork boards, you can attach them to the front of your fridge with simple push pins. This is a great way to display your children’s art or pictures and the cork board will make them easier to remove when you need to clean the fridge.

Command Strips

If you don’t want to go through the hassle of mounting a magnet board, you can also consider using command strips that are very easy to install and can be used on any non-porous surface. The best part is that you can add and remove them whenever you want, without damaging the surface!

What To Use Instead of Regular Magnets

Can You Put Magnets on a Stainless Steel Dishwasher?

Whether you’re displaying vacation mementos or children’s artwork, refrigerator magnets can be an inexpensive and fun way to personalize your home. However, not every stainless steel finish is magnetic enough to support these nifty little adornments, so it’s important to know the answer before buying your next fridge.

Typically, stainless steel is made of an alloy (combination of different metals) with a combination of nickel and chromium mixed in. These ingredients are what create the stainless steel’s ability to hold magnets.

The presence of nickel in stainless steel helps to keep it from cracking and also allows it to add more carbon, which gives the material its strength. However, more than 2 percent of nickel can interfere with the atoms’ “magnetic moments,” which are what allows them to hold magnets.

This is why some stainless steels can’t stick to magnets while others are more prone to them. That’s why you may want to avoid using magnets on your stainless steel refrigerator if it’s not ferromagnetic, which is the only type of stainless steel that can still support magnets on them.

Do Magnets Stick to 304 Stainless Steel?

Stainless steels are usually non-magnetic, but some grades can be slightly magnetic due to processing. This can make it important to understand whether a certain grade of stainless steel will keep magnets from sticking to its surface.

304 stainless steel is an austenitic (FCC) stainless steel and is not magnetic as a result of its nickel alloy content. The nickel stabilizes the austenitic microstructure and prevents it from reverting to a ferritic microstructure during cooling.

Ferritic and Martensitic Stainless Steel Are Magnetic

The most common types of stainless steel are ferritic and martensitic, with the martensitic types being the most magnetic. The ferritic varieties are also the most rust-resistant, making them ideal for food processing and marine environments.

Why Do Magnets Stick to Stainless Steel Refrigerators?

Stainless steel is a popular material for appliances because it looks great and is durable. However, it can be difficult to keep clean and free from fingerprints.

One of the easiest ways to maintain your stainless steel appliances is by removing any magnets that may be hanging on your refrigerator or other kitchen items. This helps to prevent the formation of unsightly magnet marks that can mar your beautiful fridge.

Some people have long nails and use them to pick up magnets from the refrigerator or other surfaces in their homes. These long nails can scratch and mark stainless steel surfaces, so it is important to be aware of how these things can affect your fridge.

If you have a lot of different magnets, it is best to take them off before using your fridge. This will help you avoid any damage to the surface of your appliance, as well as magnets damage well as protect your hands from scratches and other injuries that can occur when picking up magnets.

There are many types of stainless steels, and each has a different atomic arrangement that influences whether or not it is magnetic. Generally speaking, ferritic stainless steels are magnetic while austenitic stainless steels are not.

Ferritic and austenitic stainless steels are both made from iron but they have different atomic arrangements. The atoms in ferritic stainless steel have a body-centered cubic crystal structure and the atoms in austenitic stainless steel have a face-centered cubic crystal structure.

Will a Magnet Stick to 100% Stainless Steel?

Are you confused about whether or not a magnet will stick to 100% stainless steel? This question can be confusing because there are many different types of metals and alloys.

The answer to this question depends on the chemical composition and atomic grain structure of the alloy. It also depends on the amount of cold-working that has occurred during fabrication, and it is a case by case decision.

Stainless steel is an iron-based alloy that has excellent corrosion resistance and is strong. It can be used in a variety of applications, and is one of the most popular types of metals in use.

There are many types of stainless steel and they differ in their atomic grain structure, chemical composition, and the amount of cold-working that has taken place during the manufacture process. Some of the more common varieties are ferritic and austenitic, while duplex alloys contain a combination of austenite and ferrite.

Martensitic and Duplex Stainless Steel Are Magnetic

A martensitic stainless steel is magnetic because of the iron content that it has. The iron can help form a ferrite complex which is a highly magnetic material.

Austenitic Stainless Steels Are Non-Magnetic

The chromium and nickel content of austenitic stainless steels makes them non-magnetic. This is because the nickel changes the physical structure of the steel, making it less magnetic.

Do Magnets Leave Marks on Stainless Steel?

Stainless steel refrigerators are popular because they have a sleek, clean look. However, they are susceptible to rusting and scratches if not properly cleaned. To prevent these, use a cleaner that doesn’t contain bleach or chlorine, which can stain and damage newer stainless steel refrigerators.

Rub gently on the gray magnet marks. Wipe until the spots fade away. Finally, wipe the door with clean water. Best magnets for stainless steel fridge?

Do Magnets Leave Marks on Stainless Steel?

Generally, magnets don’t stick to most stainless steel appliances. The reason is that they have nickel mixed with them to create a sturdy structure, which makes the metal non-magnetic.

Some types of stainless steel, though, are very magnetic. These are ‘400’ series stainless steels (18% chrome plus 8-10% nickel), which can be made magnetic by cold rolling the panels.

If you have a magnetic stainless steel fridge, it might not be worth replacing it with another. Besides, you might find it difficult to install a new face-panel if you don’t have enough wall space for it.

How to Remove Gray Scuff Marks from a Stainless Steel Fridge Door

To remove gray scuff marks from a stainless steel refrigerator door, scrub it lightly with baking soda. Baking soda is a mild abrasive that won’t scratch the stainless surface and will help get rid of any dirt buildup that caused the marks.

How to Clean a Magnet Stain from a Stainless Steel Appliance

If you have a magnet stain on a stainless steel appliance, try Motsenbocker’s Lift Off. This will help to eliminate most stains, including magnet stains. It works by creating a barrier that prevents the stain from being absorbed by the stainless steel surface itself.

Is It OK to Put Magnets on a Stainless Steel Refrigerator?

Stainless steel refrigerators are all the rage these days, but they don’t always make for the best place to post those coupons, art projects and permission slips that keep accumulating. They also can make surfaces look cluttered, especially when you have to bend over to pick up all the magnets and pieces of paper that fall out.

The answer is no, magnets are not safe to stick on stainless steel refrigerators! The main reason that most appliances and refrigerators made of stainless steel don’t hold magnets is because of the nickel content in the metal.

This is why stainless steel fridges are mainly made from austenitic stainless steel. This is a type of stainless steel that is not magnetic because it has nickel, manganese and carbon alloyed into the material.

But the good news is that there are a few newer stainless steel finishes that are actually magnetic again. You can still use magnets on these newer stainless steel fridges and refrigerators to keep track of important notes and reminders, but there are a few things you should do differently with them.

1. Use a Magnetic Board

You can get magnetic boards that hang from suction cups to create a surface for posting your shopping list or highlighting a child’s good grade or art project. Some of these boards use a strong double-sided tape to hold them in place. However, this can leave residue on your fridge when you take the board off. If you want to avoid leaving a mark on your stainless refrigerator, use a magnetic board that has plastic protection or a vinyl cover.
