Microwaves that get a lot of use are subject to wear and tear, so knowing how to remove scratches from black plastic microwaves is an easy way to keep yours looking pristine no matter how long it’s been in service. If you’re interested in microwave types, check out our post on learning about flatbed microwaves and recirculating microwaves.
Like all kitchen appliances, the best microwaves on the market are liable to collect scratches and dings over time, but thankfully most minor cosmetic damage is easy enough to take care of yourself. These methods can also be helpful when trying to repair light damage to microhood combination microwaves.
Light scratches on a black plastic microwave, a plastic surface on a stainless steel microwave, or other black appliances can occur due to anything from microwave food covers with sharp corners to pets. There are two simple methods of removing scratches from black plastic microwave exteriors aside from purchasing appliance touch-up paint or plastic scratch remover. Both use products you likely already have in your home and are quick and fairly easy.
Most light scratches on black plastic microwaves can be removed simply and easily with soapy water or toothpaste and a few clean, non-abrasive cloths.
Remember to only use a clean cloth made from microfiber or cotton and never anything abrasive like sandpaper. Also, keep in mind that the following methods may not be effective on deep scratches.
Tools Needed: white toothpaste, 2 clean damp clothes, clean dry cloth,
Time Required: 10 minutes
Though specialized scratch removers for plastics are available, they aren’t generally any more effective than the most common DIY methods, making them a needless expense most of the time.
Can WD 40 remove scratches from plastic surfaces?
It’s a common misconception that WD 40 can remove scratches from plastic surfaces, including black plastic appliances. While it’s great for lubricating tools and removing water from metal, it won’t remove scratches from plastic.
Can using toothpaste to remove scratches from plastic damage it?
No, though the fine coarseness of most toothpaste is part of the reason it works to remove scratches, it’s not generally abrasive enough to do further damage to most plastic surfaces, paint, or finish.
Should I use a specialized scratch remover product to remove microwave exterior scratches?
It’s a common question, and while you can find products made specifically to remove scratches from plastic surfaces, they’re not necessary to spend money on, since DIY methods using soapy water or toothpaste are usually just as effective. Remember, however, that these methods may not work on deeper scratches.
