Stepping out on a fluffy and warm bathmat can sound luxurious to your mind. However, their regular cleaning is equally important. Bathmats collect soapy water, grease, and germs while you use various products for cleaning in your bathroom. They would not contribute towards a hygienic bathroom if not cleaned properly and regularly. So, when you see any discolouration black mildew marks and notice a bad smell, wash or replace them. Do not keep using one for a long period.
