How to Remove Scratches from Stainless Steel
Stainless steel is favored for its sleek look and durability. It’s an excellent choice for cookware, kitchen appliances, sinks, fixtures, and other items around the house and workplace. Unfortunately, whether it’s a microwave, dishwasher or refrigerator, stainless steel can become scratched.
You don’t have to live with scuffed up steel forever, though! Follow these simple steps to remove scratches or scrapes on your stainless-steel appliances. One thing to keep in mind: Be sure to only apply these techniques on stainless steel that does not have a protective clear coat or synthetic surface applied.
Fine Scratches
To remove fine scratches, cleaners such as Comet, Revere Stainless Steel, and Copper Cleaner can be used to gently buff stainless steel. If you can’t find any of those, appliance manufacturers often make their own cleaners that are easy to find at home improvement stores. Minor scratches can also be concealed with the use of a stainless-steel polish. Unfortunately, you must reapply the polish on a frequent basis to keep your products looking great, but this may be the best method for appliances covered with protective film.
