Keep the microscopic spores that cause mold and mildew from settling down in your bathroom for an extended stay. The keys to preventing mildew in the bathroom are to keep moist air moving, surfaces and textiles dry and soap scum under control. Use a simple solution you make yourself to clean bathroom surfaces.

Step 1

Turn on a vented exhaust fan while showering to move moist air out of the bathroom. Wipe the shower or bath walls down with a towel, squeegee or sponge at the end of the shower. Dry the shower curtain and hang it outside the tub or shower to dry. Hang towels, washcloths and bathmats so they can dry.

Step 2

Deep clean the bathtub, shower area and shower curtain once a week with a mixture of 1 cup chlorine bleach, 1 tablespoon ammonia-free detergent and 1 gallon of water. Scrub grout and tight corners with an old toothbrush. Let the mixture sit on surfaces for about 10 minutes, rinse and dry completely. If the shower curtain is washable, machine wash, adding bleach with the detergent. Soap build-up on showers, bathtubs and shower curtains provides a breeding ground for mold.

Step 3

Do laundry regularly to avoid big piles of laundry and dirty towels in the bathroom. Dirty, damp clothes piled in dark places encourage the growth of mold

Step 4

Light up the bathroom and keep it cool. Mildew and mold love dark, warm places places. Leave the curtain open or keep the bathroom light on for a while after a shower to help inhibit mildew formation. Run the air conditioner or a dehumidifier during hot, humid months.
