How to Clean a Bath Mat. Most bath mats can simply be cleaned in a washing machine. Here's how to do it without damaging the mat.
Set your washing machine's water temperature according to the color of your bath mat (hot for white, warm or cold for colors) or according to the bath mat's care label instructions.
Use mild detergent.
Set your dryer at low temperature and tumble dry, or hang or spread the mat in the shade until dry.
Brush bath mat lightly to refluff.
