Why Does Cultured Marble Turn Yellow?

Before diving into how to clean cultured marble that has yellowed, it’s essential to understand why cultured marble can turn yellow. Several factors can cause this discoloration:

Now that we know why cultured marble yellows, let's explore how to clean cultured marble that has yellowed and restore its former beauty.

Step-by-Step Guide: How to Clean Cultured Marble That Has Yellowed

1. Start with a Mild Cleanser

The first step in cleaning yellowed cultured marble is to use a non-abrasive, mild cleanser. Abrasive cleaners or scrubbing pads can scratch the surface and damage the protective gel coating, so it’s essential to use gentle materials. A simple warm, soapy water mixture can do the trick.

• What You’ll Need:
  • Mild dish soap or a cleaner specifically designed for cultured marble.
  • Warm water.
  • Soft microfiber cloth or sponge.
• Instructions:
  • Mix a few drops of dish soap with warm water.
  • Dampen the microfiber cloth or sponge and gently wipe down the surface.
  • Focus on removing any surface-level dirt, grime, or soap scum that could contribute to yellowing.

2. Use a stronger cleanser

If the surface-level cleaning doesn’t remove the yellowing, the next step is to try a stronger cleanser. Very difficult stains can be treated with a cleaner such as CLR (Calcium, Lime, Rust) or Lime-a-way  Be sure to follow the label instructions and rinse well after use. Do not let these harsh cleaners soak, wipe off quickly.

3. Use vinegar and water and polishes to keep hard water stains from forming

Cultured marble can lose a lot of its luster from hard water stains, which can give the illusion of discoloration. There are many cleaners that can be used. If you’re not sure it’s safe rub the cleaner between your fingers; if you feel any grit don’t use it. However, if your product has a matte finish, a mild abrasive cleaner can be used occasionally. If you are unsure of a cleaner read the label on the cleaner container.

Regular cleaning is recommended to keep your marble looking its best. If you have not cleaned it on a regular basis and soap scum and hard water spots have collected, you can use a squeegee or a Formica sample chip to scrape the walls of your tub surround or shower. You can also mix equal amounts of water and white vinegar, which is a good cleaning solution to take off water spots.

4. Polish the Surface for Shine Restoration

Avoid using sharp objects or toys on the surface that could scratch it. One thing you can do to keep the surface easy to clean is use a turtle wax about once a year. You can wax the surface with an automotive turtle wax or Gel Gloss (Gel Gloss is a wax made especially for gel coated finishes. It comes in a pink can and can be found at most hardware stores). If you use a regular car wax that is blue, stay away from the caulk lines because they can turn the blue color.

• What You’ll Need:
  • Cultured marble polish or automotive wax.
  • Soft cloth or buffer.
• Instructions:
  • Follow the product instructions to apply the polish or wax to the surface.
  • Use a soft cloth or buffer to work the polish into the cultured marble in circular motions.
  • Buff until the surface shines and the yellowing is less noticeable.

How to Prevent Yellowing of Cultured Marble

Now that you've learned how to clean cultured marble that has yellowed, here are a few tips to keep it looking fresh:

• Use the Right Cleaning Products: Avoid harsh chemicals like bleach or ammonia, which can break down the protective gel coat.
• Wipe Surfaces Regularly: Keep the surface dry and free of soap scum by wiping it down with a soft cloth after each use.

Conclusion

While yellowing cultured marble can be frustrating, it’s often possible to restore its beauty with the right cleaning techniques. By using mild cleansers and sometimes a stronger cleanser, you can learn how to clean cultured marble that has yellowed and keep it looking like new. Don’t forget that water is the enemy to many surfaces. Be sure to squeegee and dry your cultured marble surface after each use to keep it always looking like new.
