How to Remove Mildew From a Shower Floor Mat

A rubber mat on a shower floor keeps you safe from slips and falls. Most shower mats stick to the floor with the aid of suction cups. Because the shower mat is stationary, it ends up continually sitting in hot water and steam and never has the chance to dry. This causes mildew to grow on the top and bottom of the mat. Rather than stand on a mat with mildew growth or spend money buying another one, you can clean mildew stains from the mat.

The shower area is especially conducive to mildew.
  1. Set the floor mat in your bathtub. Fill the tub with 5 gallons of warm water and add 5 cups of chlorine bleach. Allow the mat to soak for 30 minutes and turn it once during this period.
  2. Protect your skin when working with bleach or cleaners.
  3. Wear rubber gloves and scrub both sides of the mat as it soaks in the bleach solution. Drain the bathtub and rinse the mat on both sides with warm water.
  4. A little scrubbing helps remove mildew stains.
  5. Mix equal parts of baking soda and white vinegar in a bowl. Use the foaming mixture to clean any remaining mildew on the mat. The mildly abrasive baking soda and vinegar mixture can kill remaining mildew and remove accompanying stains and odors.
  6. Rinse the mat with warm water. Stand it against the side of the tub to dry or place it outside where the sun can aid in drying.

Things You Will Need

  • 5 cups chlorine bleach
  • Rubber gloves
  • Scrub brush
  • Bowl
  • Baking soda
  • White vinegar


  • Mildew transfers from the bottom of a shower mat to the shower floor. Clean the shower floor using the same supplies while the mat soaks.
  • Undiluted vinegar is an effective mildew killer for shower surfaces.
  • Stand the shower mat up against the side of the shower after each use. Keeping the mat dry helps prevent mildew from returning.
