Run the bathroom exhaust fan, air-conditioner or dehumidifier while you shower, and for approximately 30 minutes afterward to reduce moisture in the air. Leave the door open afterward, too, so that moisture doesn’t accumulate in the room.
Wipe the tub and faucets with an absorbent cloth and the shower walls with a squeegee after each shower use.
Hang washcloths and bath towels on a bar or hook immediately after use, or launder them directly afterward. This helps them dry more quickly, which prevents mildew and musty odors.
Close the toilet lid when flushing to reduce the spread of bacteria, and clean the toilet at least once each week. Use a commercial toilet bowl cleaner, or scrub the inside of the bowl with baking soda, vinegar or borax. Wipe the tank and handles with an all-purpose cleaner, or use a mixture of equal parts water and vinegar.
Scrub the sink and tub with a mild abrasive cleaner once each week. Stir water in baking soda to make a scouring paste, and use a mixture of water and vinegar to clean scum from the mirror and shower stall.
Vacuum the floor and use the attached nozzle to remove hair from other surfaces when the bathroom is dry. Scrub it weekly with the appropriate cleanser for your floor type.
Mix 1 cup of bleach per gallon of water for mold and mildew removal. Sponge this into moldy crevices or use it in a spray bottle. Allow the solution to set for a few minutes, and then scrub it away with a wet cloth, as recommended by the Good Housekeeping website.
Clean the drains every month or two with a combination of vinegar and baking soda. Pour approximately 1/4 cup of baking soda on the drain, then pour an equal amount of vinegar over it. When it stops foaming, run hot water down the drain to rinse it and remove any remaining clogs.
