Can you get scratches out of stainless steel?


You can remove scratches on stainless steel by using special cleaners. They contain a dry powder that you combine with water to apply to the metal. Some appliance manufacturers have their own special cleaners, so inquire with them first.

How does toothpaste work to remove scratches?

When you slowly rub toothpaste onto a smooth surface, it essentially sands the scratches. However, toothpaste is ineffective against deep scratches.

Does baking soda remove scratches from stainless steel?

Baking soda is quite effective in removing light scratches on stainless steel. It has a powdery texture that serves as a gentle abrasive. Add water and baking soda to make a paste, put it to the surface of the metal and scrub lightly. Then wipe off the baking soda and wipe the surface with a damp cloth.
