Cultured marble showers are durable and beautiful. Cultured marble is a mixture of natural marble stone and polyester resin, which gives it added strength. The material is not porous like marble; it does not need periodic sealing. Cultured marble is also more stain-resistant than the original stone. Use appropriate cleaning materials and non-abrasive items to keep your cultured marble shower clean and scratch-free.

Step 1 - Wipe Spills Immediately

Preventive maintenance can go a long way in keeping your cultured marble shower looking new. After every shower, use a squeegee to wipe the sides of the shower walls and remove the water. Doing so will prevent excessive accumulation of dirt, soap scum, and hard water stains. If any colored material such as hair color, paint, or chemically reactive cleaning products spill on the cultured marble, wipe the material immediately. Doing so will prevent the formation of stains that can be difficult to remove later.

Step 2 - Use Vinegar to Remove Hard Water Stains

Hard water stains can develop on the shower surface over time. To remove these stains safely, use vinegar. Fill a spray bottle with vinegar and spray the affected areas on the shower surface. Wait an hour and wipe the stains with a soft cloth or sponge. If the stains are still there, repeat a few more times.

Step 3 - Use Turpentine or Paint Thinner to Remove Stubborn Stains

Stubborn stains, such as paint or hair dye, may be difficult to remove. Paint thinner or turpentine can improve chances of stain removal. Application of such materials must be done with caution and only after testing on an inconspicuous area. If the tested area shows any discoloration or damage, avoid using these products. If the testing is successful, apply a small quantity on a soft cloth and rub the stained area. Rinse with water and repeat if needed.

Step 4 - Refinish the Surface Annually

Cultured marble showers can lose their shine. To refinish the surface, use a finishing product recommended by the manufacturer. CounterTop Magic and Gel Gloss are generally recommended. From time to time, check the caulk in the seams to make sure it is intact. Never use abrasive cleaners with harsh chemicals to clean your cultured marble shower. Only use soft cloth or non-abrasive sponges for cleaning.

Though cultured marble is very durable, it can be prone to cracks if it is not handled properly. Avoid dropping heavy or sharp objects in the shower. Cracks and breaks on the surface cannot be repaired, but scratches and minor chips can be repaired.
