Therefore, even though they are non-porous, they still need appropriate cleaning. So, learn how to clean cultured marble shower through the methods and steps mentioned below.

Method 1: Cleaning With Mild Soap

It is better to do a regular clean-up for your cultured marble shower to maintain the look and cleanliness. Mild soap is a light cleaning agent that will serve regular cleaning without causing any wear & tear to the shower surface. Follow these steps to carry on with the approach:

Step 1: Wet the Cultured Marble Surface

  1. Use a clean & damp cloth for the purpose.
  2. Run it over the cultured marble surface to wet it slightly.

If you recently took a shower, and the cultured marble surface is already wet, then you can ignore this step!

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 your stains are too tough for the vinegar to break down, you’ll need to move on to something more powerful. Either turpentine or paint thinner should do the trick. Start with paint thinner and work up to turpentine if needed.
