    The surface of your Shower Floor may be cleaned with a mild soap solution in warm water using a soft cloth.

    When using a cleaner product, carefully read the label to ensure that the cleaner is safe for use on the material. Stubborn stains can be cleaned using “Soft Scrub®” by Clorox® , “Spic-n-Span®.” , Mr. Clean Magic Erasers, or like products.

    Do not allow cleaners to sit and soak on the surface. Wipe surface clean and rinse completely with water immediately after cleaner application. Rinse and dry any over spray on nearby surfaces.

    Never use abrasive scouring powder or steel wool pads, as they will scratch the surface. A periodic coating of a high quality marine or automotive polish will help retain the finish.

    As a company committed to continuous improvement, the specifications included here are subject to change without notice.
