How do I get rid of mold in the bathroom?

Concerns & risks

You were trying to enjoy a relaxing shower, but you noticed dark spots of mold spreading on the grout.

Everyday mishaps add up.

Causes & evidence

Clean with soap and water or a mold product; fix moisture. See cleaning chemical safety.

What to do

1. Ventilate.
2. Scrub with detergent.
3. Fix the moisture source.

Common mistakes: Common mistakes: just cleaning the mold without fixing the moisture. Mold returns if the bathroom stays damp. Run the exhaust fan during and after showers, or open a window. Wipe down wet surfaces. Fix leaks. Wear gloves and eye protection when cleaning mold. Never mix bleach with other cleaners. For large areas, more than about 10 square feet, consider professional help. Porous materials like caulk can hold mold deep inside; if mold keeps coming back, replace the caulk. If someone in your home has asthma or allergies, they may want to avoid the cleaning. Make sure the area dries fully after cleaning. A squeegee after showers helps.

Speed Man tip: Run the fan after showers.

Wrap-up: Air. Scrub. Moisture.
