Baking soda has as many cleaning uses for vinyl as there are types of vinyl surfaces.
Start with the floor. A sprinkle of baking soda lightly scrubbed with a wet sponge will take many stains off of a vinyl floor. Be careful to avoid soaking the floor, however, and dry it thoroughly afterward. Water can seep into seams and under edges, loosening the glue and curling the corners.
The same process works for vinyl shower curtains, bath mats and appliqués, which are prone to mildew as well as soapy residue. Curtains can additionally be machine-washed with baking soda. Add 1/2 cup (120 milliliters) with the detergent and choose the gentle cycle. (Toss in a few towels to keep the curtain from sticking to itself and clumping.) For added disinfection, pour in 1/2 cup (120 milliliters) vinegar during the rinse cycle. Let the curtain air dry; it will melt in the dryer. Let the rubbed-in paste stand on appliqués for 20 minutes or so to remove darker stains.
We've touched on just about every material in the bathroom that baking soda can clean. The substance we target on the next page is somewhat less substantial.
