The 10-Second Fix:
1. Apply White Vinegar:
Soak a soft cloth or sponge with white vinegar. Vinegar’s mild acidity helps break down the rainbow discoloration caused by heat or chemicals on stainless steel.

2. Wipe the Stains:
Rub the vinegar-soaked cloth over the stained area. The vinegar will quickly dissolve the stains, leaving your stainless steel shiny and clean.

3. Buff the Surface:
After wiping the stains, use a dry cloth to buff the surface to restore its original shine.

Optional Step (For Tougher Stains):
If the rainbow stains persist, sprinkle a little baking soda over the area before applying vinegar. The fizzing action from the combination of vinegar and baking soda helps lift tougher stains. Then, wipe away the residue with a clean, damp cloth.

Why This Works:
Vinegar’s acidic properties react with the oxidation or heat marks on stainless steel, effectively removing the discoloration without damaging the surface.

Baking soda adds a gentle abrasive action that helps with more stubborn stains.

Final Thoughts:
With just white vinegar and a soft cloth, you can remove those unsightly rainbow stains from your stainless steel in just 10 seconds. This quick and easy fix will leave your stainless steel cookware, appliances, or sinks looking brand new!
