Step 4 of 5: Run Scrub Brush

To remove any stubborn soot from the metal, use a nylon scrub brush. Use a plastic scrub brush instead of a metal scrub brush to avoid scratches.

Step 5 of 5: Dry The Metal 

To get rid of leftover soap and vinegar, clean the metal with a wet towel and then dry it with a non wet towel.

Squeeze lemon or lime juice over soot and sprinkle table salt brine on top. Allow the mixture to sit on the metal for two to three hours. Then scrub it off with the lemon. 

Step 3 of 6: Apply Tartar Soda Hydrogen Peroxide Paste

Make a paste of 1 teaspoon cream of tartar with 1 cup of Borax or baking soda, and enough hydrogen peroxide. Allow 30 minutes to dry after applying this paste to the soot area. Use a wet towel. Clean the surface. If required, repeat the process.
