  • how useful is the material in the particular usage.

With the answer to these points in mind and with the pros and cons listed above, you are bound to make the right decision with the material… whether it will be cultured marble or something else!

Cultured marble is a precise blend of catalyst, polyester resin, pigments and fillers that are thoroughly mixed and then placed into open molds that have previously been coated with a clear gel coat.

However, just like any other surfaces, the ones made from cultured marble get stained. Since cultured marble is a hard gel-coated, non-porous surface, it resists staining and is very easy to clean. There are some cleaning tips and tricks you should keep in mind when it comes to stains, though.

1. Water deposit stains


Most likely, water deposit stains occur because of the mineral deposits from the water that commonly sits around the drain. Therefore, this area is always getting stained. In order to fix that, here is what you need to do:

  • First, you need to moisten a soft cloth with white vinegar.
  • Then, lay the cloth on top of the hard stains, allowing it to set for a couple of hours.
  • After that, you need to remove it and rinse completely with cold water.

2. Everyday stains


Removing everyday stains from cultured marble is also very simple.  Here are the steps you need to follow:

  1. Soak a soft cloth with hydrogen peroxide and lay it on the top of the stain.
  2. Allow it to set overnight (for dark stains, a couple of hours is not enough).
  3. In the morning, rinse completely with cold water.

If the stain does not seem to be going away, here is a recipe that will help you:

  • Mix 1/4 cup baking soda, 1/4 cup vinegar, 1/2 cup ammonia, and 8 cups hot water.
  • Allow the mixture to foam, then apply it on the stains with a soft cloth.
  • Allow it to set for 5 minutes, and then rinse completely with cold water.

3. Routine cleaning


Even if your cultured marble is not stained or scratched, caring for it on a regular basis is a must, that is if you want it to look great for years to come. When it comes to routine cleaning, all you need is a soft cloth or sponge. You could also use a non-abrasive aerosol foam cleaner. Normally, this is all you need to make your cultured marble products shine. Just remember to steer clear from harsh abrasive cleaners.

4. Additional tips

Cultured marble scratches easily, so remember never to use any kind of abrasive cleansers or products on it. You should not use any type of scrubbing sponge or steel wool, either.


Never clean cultured marble when it is dry, because this will also lead to the surface getting scratched. Therefore, you should wet the surface before you get started.

Before getting started, it is also recommended to test a small area first in order to make sure that there are no averse effects to the surface or its coloring. 

If your cultured marble is scratched, a professional can easily repair the scratches and make the surface brand new.

These are the things you need to keep in mind when it comes to cleaning cultured marble. Normally, this kind of surface should not pose any problems, but it is still important to know some general tips that may come in very handy one day.
