How to Remove a Rainbow From Stainless Steel

Removing a rainbow from stainless steel involves removing a thin layer of oxide film that results from oxidation. Here are a few effective methods to remove a rainbow from stainless steel surfaces:

1. Vinegar and Baking Soda:

- Create a paste by mixing equal parts of white vinegar and baking soda.

- Apply the paste to the affected area and let it sit for about 15 minutes.

- Scrub the surface with a non-abrasive sponge or cloth in the direction of the grain.

- Rinse thoroughly with water and dry the surface.

2. Acetone or Nail Polish Remover (Non-Gel):

- Apply a small amount of acetone or non-gel nail polish remover to a soft cloth.

- Gently rub the cloth over the rainbowed area in the direction of the grain.

- Be careful not to rub too hard to avoid damaging the surface.

- Wipe off the residue with a damp cloth and dry the stainless steel.

3. Isopropyl Alcohol:

- Dampen a soft cloth with isopropyl alcohol (rubbing alcohol).

- Wipe the affected area in the direction of the grain.

- Continue wiping until the rainbow has disappeared.

- Rinse the surface with water and dry thoroughly.

4. WD-40 or Multi-purpose Oil:

- Spray a small amount of WD-40 or multi-purpose oil onto a cloth.

- Gently rub the cloth over the rainbowed area until the discoloration disappears.

- Wipe off the excess oil with a clean cloth.

5. Non-Abrasive Cleaner:

- Use a non-abrasive cleaner meant for stainless steel surfaces.

- Follow the instructions on the product label for application and rinsing.

- Thoroughly rinse the surface with water to remove any remaining cleaner.

Remember to test any cleaning solution on a small, inconspicuous area first to ensure it doesn't damage the stainless steel. Also, always rub in the direction of the grain to avoid any potential scratching or damage to the finish. It may be necessary to repeat the chosen method to completely remove the rainbow effect.
