Mold & mildew

Ventilate and put on gloves, a mask, and goggles. On tile and caulk, apply a mold stain remover, let it work, then rinse and dry. Don't spray chlorine products across a painted ceiling; spot-treat small areas and repaint with mold-resistant paint if it's widespread. The real fix is lowering humidity.

Surface mold can be cleaned: lay a mold stain remover on the caulk, leave it 10 to 15 minutes (30 for stubborn spots), then rinse and dry. If the caulk is still black afterward, mold has grown into it and cleaning won't remove it. Cut out the old caulk, let the joint dry completely, and recaulk.

When humidity is high, set the water to its lowest level or switch to vacuum-only. Run a dehumidifier or the AC first, and mop once the floor stops sweating. Dose solution at the low end, and dry the pads, dirty tank and wash tray after every run so nothing turns moldy or smelly.

The black slime in the wash tray is biofilm that forms when dirty water, hair and organic matter sit in the dock; black dots on the filter are usually mold. Remove the tray and filter, scrub them with a soft brush, dry them completely, and clean more often so water never sits for long.

Scrub a short stretch with a stiff brush and plain water. If the black lightens right away, it's soap scum, body oil and dirt, and a grout cleaner will lift it. If it's spotty, sits in damp corners and comes back after you wipe it, it's usually mold, which also needs a mold remover and better ventilation.
