3. Treat Stubborn Yellowing with Hydrogen Peroxide
- Soak a paper towel or cloth in 3% hydrogen peroxide.
- Lay it over the yellowed areas and let it sit for 15–30 minutes.
- Remove the towel and rinse the area with warm water.
- Hydrogen peroxide acts as a mild bleaching agent, effectively removing discoloration without damaging the Corian.
4. Use White Vinegar for Hard Water Deposits
- Mix equal parts white vinegar and water in a spray bottle.
- Spray onto the sink and let it sit for 5–10 minutes to dissolve mineral deposits.
- Scrub gently with a sponge and rinse thoroughly.
5. Buff the Surface with Bar Keeper’s Friend (Optional)
- Apply a small amount of Bar Keeper’s Friend to a damp sponge.
- Rub the yellowed areas in small, circular motions.
- Rinse thoroughly with warm water and dry.
- Ensure you use only a Corian-safe abrasive cleaner to avoid scratching the surface.
Maintenance Tips
- Dry the sink daily: Wipe it down with a microfiber cloth after each use to prevent water spots and staining.
- Avoid harsh chemicals: Never use bleach, ammonia, or harsh abrasive cleaners, as they can damage the finish.
- Regular deep cleaning: Perform a hydrogen peroxide treatment once a month to keep the sink bright.
- Prevent scratches: Use soft scrubbers and avoid placing sharp or heavy objects directly in the sink.
By following these steps, your Corian sink should look white and fresh again!
