How can I prevent mold growth in my bathroom?
NOW: Repair leaky pipes within 24 hours. Wash rugs and window curtains once a week to keep their fibers from trapping moisture. Replace plastic shower curtains with hemp, cotton, or linen ones; they allow air to penetrate so the curtain and stall dry faster.
AFTER A SHOWER: Towel off your shower door and walls and leave the bathroom door open. Keep the humidity in the bathroom between 30 to 50 percent by using a fan or dehumidifier or opening a window.
EVERY 3 YEARS: Have a mold remediator inspect your bathroom, or do it yourself with the Examinair Home Mold Test Kit ($400; examinair.net).
