Keeping your bathroom looking bright and clean can be a challenge. Over time, countertops can develop yellow stains that are unsightly and difficult to remove. If you’ve noticed your once-pristine white countertops now have a yellow tint, don’t panic. With the right techniques, you can get them looking like new again.

Tips to Prevent Countertops Turning Yellow


  • Overusing bleach can cause yellow stains.
  • Letting moisture sit causes yellowing on counters.
  • Poor ventilation encourages yellow stains.
  • Harsh chemicals like ammonia damage countertops.
  • Reseal natural stone yearly to prevent stains.
  • Baking soda paste lifts stains on laminate.
  • Vinegar spray cuts through stains on marble.
  • Hydrogen peroxide removes stains on quartz.
  • Ceramics needs non-abrasive cleaners like Lysol.
  • Prevent stains by wiping after use and using trivets.

What Causes Yellow Staining on Bathroom Countertops?

There are a few common culprits behind yellow bathroom countertop stains:

  • Overuse of bleach – Bleach is a powerful disinfectant, but it can damage countertop seals over time, allowing stains to set in. The bleach itself can also react with the material and cause discoloration.
  • Insufficient sealing – Natural stone counters like marble and granite need to be regularly resealed to prevent stains. If the sealant wears away, exposure to moisture and cleaning products can cause yellowing.
  • Poor ventilation – Bathrooms with inadequate ventilation allow moisture to accumulate on surfaces. Prolonged exposure to moisture encourages yellow stains on countertops.
  • Harsh chemicals – In addition to bleach, other harsh cleaning products like ammonia and acetone can damage counter finishes and cause discoloration.
  • Sunlight – UV exposure from natural sunlight can slowly change the color of some countertop materials, especially lighter-colored stones.
  • Age and wear – Over many years of use, counter finishes simply degrade and stains accumulate. This natural aging causes yellowing on older countertops.

How to Remove Yellow Stains from Bathroom Countertops

The good news is that yellow countertop stains can usually be removed with some simple cleaning methods. Here are effective techniques for different countertop materials:

Laminate Countertops

For laminate counters, create a paste of baking soda and water. Apply the paste to stained areas and let sit for 5 minutes before wiping clean. The baking soda will help lift stains without damaging the laminate surface.

You can also use hydrogen peroxide. Soak a clean rag with peroxide and gently wipe down the yellowed areas of the countertop. Let it sit for a few minutes before rinsing. Be careful not to scrub too hard.

Formica Countertops

Formica is similar to laminate, so the same cleaning methods apply. Make a baking soda paste and apply it to yellowed Formica. You can also use a non-abrasive all-purpose cleaner instead of baking soda. Spray it on, let it sit briefly, and wipe it away.

Marble, Granite & Natural Stone

For porous natural stone, use a specially formulated stone cleaner. Apply it to stained areas, lightly scrub with a soft brush, and rinse away. This will lift stains without eroding the stone finish.

You can also make a gentle cleaner by mixing dish soap with warm water. Use a microfiber cloth to wipe down yellowed areas. Rinse thoroughly. Avoid harsh chemicals that can etch the natural stone.

Cultured Marble

For cultured marble counters, spray a mix of equal parts white vinegar and water directly onto yellowed areas. Allow to sit briefly before wiping clean with a soft cloth. The vinegar will cut through stains without damaging the marble surface.

Quartz Countertops

Quartz is resistant to stains, but yellowing can still occur. Make a baking soda and water paste and apply to the affected areas. Let it sit briefly before rinsing and wiping clean. For tougher stains, use a soft cloth dampened with hydrogen peroxide.

Ceramic & Porcelain Tile

For ceramic and porcelain bathroom counters, apply a non-abrasive bathroom cleaner like Lysol Daily Cleanser. Spray onto yellowed areas, wait 5-10 minutes, and wipe clean. Baking soda can also work to lift stubborn yellow stains on ceramic and porcelain.

How to Prevent Future Yellow Staining

Once you get your counters stain-free, you’ll want to take steps to prevent future yellowing. Here are some tips:

  • Seal natural stone countertops annually to protect them from moisture and staining. Use a product specifically designed for the stone.
  • Avoid using bleach and harsh chemicals like ammonia to clean counters. Use mild dish soap instead.
  • Open windows or run bathroom fans to improve ventilation and prevent moisture buildup.
  • Wipe counters down after each use to prevent mineral deposits from forming.
  • Use cutting boards and trivets to protect counter surfaces from stains.
  • For a quick cleaning boost, spray counters with a mix of vinegar and water.

Know When to Call a Pro

If you’ve tried these techniques and still can’t get those yellow stains out, it may be time to call in a countertop professional. They have commercial-grade cleaners and tools to deep clean and resurface counters. This is especially important for natural stone counters that may need resealing.

With some persistence and the right cleaning methods, you can get your stained bathroom countertops back to their former glory. Be sure to take steps to prevent future yellowing too. Follow these tips and you’ll keep your counters looking fresh and bright.
