Before You Start

Before cleaning, ventilate the bathroom and protect surrounding surfaces such as metal fixtures and grout lines. Test any cleaner on a small, inconspicuous area to ensure it won’t dull the finish. Allow 15–30 minutes for the cleaner to work on soap scum, then proceed with gentle scrubbing. Avoid acidic or abrasive cleaners on cultured marble, which can etch the surface and cause lasting damage. Plan for a total cleaning time of 20–40 minutes depending on the shower size and buildup.
