How to remove mildew
Mildew is a moisture problem first and a stain second. Dry it out, ventilate, treat with vinegar — and make sure it dries fully or the spores return.

How to Get Mildew Out of Carpet
Mildew on carpet happens when moisture gets trapped in the fibers, and you need to kill the spores and lift the stain before it spreads. White vinegar kills mildew, baking soda absorbs odor, and a stiff brush lifts the residue from deep in the pile. Work quickly—mildew weakens carpet backing and can spread to the pad underneath.
MildewCotton
Mildew Smell on Cotton — How to Get It Out
Mildew smell on cotton clothes comes from mold spores that thrive in damp fabric, and you can eliminate it with white vinegar and baking soda before a hot wash. Cotton is durable enough to handle aggressive odor treatment, so you can use heat and alkaline boosters without worry. The key is to kill the spores and neutralize the musty odor at the same time.
MildewLeather
Mildew on Leather — How to Get It Out
Mildew on leather shows up as fuzzy gray or white patches that smell musty, and you can remove it with isopropyl alcohol and careful wiping. Leather is porous and can't tolerate soaking or harsh scrubbing, so work gently and let it dry completely between steps. Act quickly—mildew eats into the hide and weakens it over time.

Mildew on Upholstery — How to Get It Out
Mildew stains on upholstery come from trapped moisture and mold spores, and you can remove them with white vinegar, baking soda, and careful brushing. The key is to kill the mildew, lift the stain, and dry the cushion or fabric completely so it doesn't return. Always test your cleaning solution on a hidden spot first — upholstery fabrics vary widely in how they tolerate moisture and acid.

Mildew Stains on Wood — How to Remove Them
Mildew stains on wood appear as dark gray or black patches caused by surface mold, and you can remove them with white vinegar and a scrub brush if you act before the spores penetrate deep into the grain. Unfinished wood needs more aggressive treatment than sealed or painted surfaces, so adjust your pressure and product strength accordingly.
