Step 2: Apply a Mild Soap Solution Over the Surface

  1. Prepare the soap solution by mixing it with water.
  2. Get a spray bottle and fill it with the soap solution.
  3. Spray the soap solution directly onto the cultured marble surface.

You can also use a cloth dampened with soap solution to wipe clean the surface. (Optional)

Step 3: Wipe Off the Solution From the Showers Surface

  1. Use a soft rag to wipe off the cleaning solution. (Soft rags will prevent damage or scratch to the surface)
  2. Make circular movements with the rag on cultured marble shower surfaces.
  3. Continue this movement until you wipe away all of the soap solutions.
  4. If you find some stain or build-up remaining after this cleaning, then respray some soap solution.
  5. Now wipe it with the rag, and continue the process until the surface is clean & dry.
  6. Switch to a clean rag or cloth if the one you are using gets too wet.

Method 2: Cleaning With Vinegar Solution

Cultured marble showers can get mild build-ups because of hard water stains or soap scum. Therefore, at times the soap solution may not be sufficient to clean it all up. Hence, this method will be your go-to solution in this case. 

Step 1: Wipe Off the Spills Immediately

If you are using any particular herbal remedy (like turmeric or hibiscus paste) while bathing or spilled something by mistake over the cultured marble surface, consider wiping it off immediately. Otherwise, they can tend to stick. With correct methods of cleaning, you can increase its life.

  1. Keep a squeegee in your washroom.
  2. Use it to remove water from the wall sides. In addition, it will prevent the accumulation of hard water stains or soap scum.
  3. Use a sponge or cloth to remove stains such as hair color, paint or others, immediately.
  4. It will prevent the formation of difficult-to-remove stains.

Step 2: Spray Vinegar Onto the Affected Surfaces

  1. Buy vinegar solutions from the online or offline market.
  2. Fill it into a spray bottle. (Prefer a big spray bottle to avoid frequent refills)
  3. Start spraying over the area of build-up or tough stain.
  4. Let it settle down for a couple of hours.
  5. Use a soft cloth to wipe off the stain or build-up. (You can also use a sponge)
  6. In case you see more stain or build-up remnants over the surface, repeat the process.


If you have tough stains resistant to the vinegar cleaning solution, you should use Turpentine or Paint Thinner for the purpose. However, some stubborn stains need intense cleaning. Therefore, Turpentine can be an ideal pick!
