Mildew Removal from Clothes / Misc. Cloth

Oxi-clean is a good product to get out mildew from cloth. You might have to soak it for a few days but it gets the job done.

Have you tried Borax? I don't know about the stains but it will help with the odor.

Pinesol is general cleaner. It is not laundry detergent. To try to get something like black mildew out of material fibres, as it has actually permeated into the threads and is growing, the garments have to be both soaked and scrubbed with a soap designed to penetrated into the woven thread fibres. Also, water hot enough to kill the mildew spores will also be necessary.

Do you know the fabric content of the clothes- do you know if any are synthetic, such as polyester or nylon?

Try hanging them on a clothesline, in the sun.

Can you bleach them?

HUGE Thank You !

I doubt it since the cloth has a printed design.

Bleach for whites, and ammonia for colors. Don't mix the two, toxic fumes

If it was some form of synthetic, then the damage may be permanent, but a cotton comforter - is it not machine washable in a regular front loading washer?

I would suggest that you spot hand scrub with oxi-clean, or borox powder as others have said, rinse out, then wash through a full cycle in a washing machine.

If you put the comforter in the bath tub during the scrub stage, it will be easier to manage and rinse, than if you tried to do it in a sink.
