Bathrooms -- which are typically moist and often humid -- are a breeding ground for mildew. If left untreated, mildew can contribute to allergies, respiratory problems and other illnesses. A mildew-infested shower mat is unsightly and unsanitary. Fortunately, you can remove mildew from shower mats relatively easily with common household products. Some retailers now sell mildew-resistant natural rubber mats. While much more expensive than latex or vinyl, no-mildew mats can last years longer and often are stain-resistant.
Combine 30 ml (1/8 cup) chlorine bleach with 4.5 litres (1 gallon) water.
Pour the solution into a plugged bath or a large bucket.
Immerse the shower mat in the solution for three to four hours.
Rinse well and hang outside to air dry.
Toss your shower mat into the washer once a week with a few bath towels. The cloth will scrub the mat, and the entire load will come out clean. Do not dry the mat in a clothes dryer; doing so can melt the material.
To prevent skin damage, wear gloves when soaking and removing your bathmat. Combining chlorine bleach with other products -- especially ammonia or vinegar -- can create toxic fumes. Only use chlorine bleach in well-ventilated areas.
