Welcome to HMmagnets! If you have made the great decision of purchasing one or more of our awesome products, you’ll need to know how to clean them, so let’s begin!

How to Clean a Stainless-Steel Magnetic Knife Holder

Hot water and a Cloth

The easiest way to clean our magnetic stainless steel knife holders is with water that is hot and a cotton cloth, that is soft and clean, to wipe it. In general, stainless steel is rather easy to keep clean. It is best to clean it along the grain, as opposed to a perpendicular fashion. 

Mild Detergent

Should using hot water alone not clean it the way you want, apply a little bit of dishwashing liquid inside of the water – not directly onto the stainless steel.

Rubbing Alcohol

Should any grease get onto your stainless-steel knife holder while cooking, you can get rid of it using rubbing alcohol.

Baking Soda and Water

If any stains get onto your stainless-steel knife holder, you can make a paste out of baking soda and water and put that on the stain. However, baking soda is abrasive, so only use it as your last resort. If possible, test it on one spot of the knife holder to see what happens, instead of applying it to the entirety of the knife holder. Afterwards apply water to get rid of any residue and dry it with a clean cloth.

Finally, use a clean and damp cloth to get rid of any of the residue of the above products that you used. Go ahead and rinse the cloth a second time and go over it. Polish it with glass cleaner for that extra shine.

**Just a note – never use steel wool on your stainless steel. This just damages the chromium oxide layer which protects it. Also, it’s important to dry the knife holder after cleaning it to keep it nice and shiny.

How to Clean a Wooden Magnetic Knife Holder

This may attract dust, so take care to use a microfiber cloth the instant you see dust, and wipe while it is dry. Use gentle movements as opposed to force on your magnetic walnut knife holder. You can also get a soft cloth and dampen it with an actual product made for dusting, as this will help keep dry scratches at bay.

If any water marks appear that are milky in nature, remove them immediately. Put on some rubber gloves and place a cloth in water that is extremely hot. Go ahead and ring it out, making a pad. Then dampen the walnut wood with some household ammonia – just a few drops. Rub fast and light, without applying too much pressure, until the milky water marks disappear. You can then place a lot of linseed oil on it and polish it with a cloth that is soft and dry until there is no trace of the oil.

How to Clean a Magnetic Tool Holder

Regular Toothpaste

Our magnetic tool holders are made from iron and ferrite magnets. In order to clean the iron, take toothpaste and smear it across the bar. Then wipe it gently with a soft, damp cloth, getting rid of any toothpaste residue. Wipe gently again with a damp cloth, then use a dry cloth.

Baking Soda and Water

You can also use baking soda and water on it by scrubbing the bar very gently with a nylon brush. Be careful as the baking soda can scratch the surface. Then wipe away with a damp cloth, and repeat. Finish it off with a soft dry cloth.

Vinegar and Water

Lastly you can use ½ a cup water and ½ cup vinegar (both distilled) and use it on the knife holder. Wipe it on with a soft cloth, then wipe it with a cloth dampened by water, and finally wipe it with a dry cloth.

How to Clean Magnetic Dry Erase Boards

Our wide range of magnetic dry erase boards have three layers. The first layer is made from a special film layer called transparent PET. The second layer is white PET film and the third, magnetic layer is made from a rubber magnet. Don’t worry about layer 2 or 3, you just need to clean the first transparent PET layer. This is how to clean it:

Isopropyl Alcohol / Peroxide

You may use rubbing alcohol (or hydrogen peroxide) to clean your board. Use 90 or 99 percent isopropyl alcohol. Avoid the 70% ones as they don’t work so well. 

Go ahead and mix together the alcohol/hydrogen peroxide with water, apply this to a microfiber cloth and wipe the dry erase board clean. If the stains are very stubborn, you can rub the isopropyl alcohol straight onto the stain. Let it sit for a while before wiping it clean with a soft dry cloth.

Hand Sanitizer

You can use hand sanitizer on any stains, provided the concentration of isopropyl alcohol is at least 90-99%. Use the hand sanitizer directly by spraying or wiping it on a soft clean cloth, or alternately, a paper cloth. Wipe, allow it to sit for 30 seconds, then take it off with a soft clean cloth or soft paper towels.


If you would rather use a natural cleaner, apply a mix of vinegar and water. You can use one teaspoon of vinegar added to one cup of water or even 2 cups together (1 cup vinegar, 1 cup water). It is an inexpensive and natural method that can safely be used around little children. 


Hairspray usually has isopropyl alcohol inside. You can spray directly onto the stains on the dry erase board and wait about 10 minutes. Then you will need to use a very soft and clean cloth dipped into warm water that has been mixed with mild detergent to get rid of any sticky residue. Afterwards wipe with a damp soft cloth and warm water, and then dry it off with a soft cloth or paper towels. Keep in mind that you can also use spray deodorant. It contains around 95% of ethyl alcohol. 


WD-40 works wonders on a dry erase board. Simply spray it on and it will not only get rid of stains, but will polish the plastic too. Make sure to wear an apron while spraying, as it can stain clothes, and keep it away from children.


Next time you go out shopping, make sure to pick up some vinegar, baking soda, WD-40, regular toothpaste, mild detergent, plastic bowls, hand sanitizer, and at least 90% rubbing alcohol. Also buy a ton of microfiber cloths and paper towels. This way, you will be organized and ready to clean any of our wonderful products!
