Fiberlock - Shockwave Hydrogen Peroxide - Disinfectant and Cleaner - 1 Gallon - 8318

One of the few things I have tried that really does kill mildew, even in clothing, Its fairly expensive to use on clothing but it does work. Note that this is the RTU version . The concentrated version also works but is not as good for laundry as it leaves a soapy smell that is hard to wash out. I washed colors and it didn't fade them.

a perfect DISINFECTANT

Works very well.
