Keeping a refinished bathtub sparkling clean and like new for years is easy! This is what Kohler, American Standard, Lasco and other new tub manufacturers recommend:
Do clean your refinished bathtub with only non-abrasive, liquid cleaners. The best are Mira-Clean, Formula 409, Fantastik and dishwashing soap.
Do use a soft sponge or wash cloth to wipe down the surface and make sure to rinse thoroughly.
Do not use any abrasives cleansers, not even the liquid types, bleach or strong acids. All of these will destroy the finish.
Do not use steel wool, brushes or abrasive sponge pads.
Your refinished tub will look great if you spray the surface with a non-abrasive liquid cleanser and leave it sit for three to five minutes. Wipe down with a soft cloth or cleaning pad made for Teflon surfaces and make sure you rinse well to remove all the cleanser. Don’t let the cleanser sit for more than five minutes though. About every six months use a polymer based polish to refresh the finish.
