DO NOT use bleach, use oxyclean.
I've tried Oxyclean. It didn't cut it.

Spray it with a stronger concentrate of Oxyclean and keep it wet for a
longer period, rubbing it with a cloth, then spraying it with the
Oxyclean. Bleach will "bleach" it white. I have used this to get rid
of mildew on the headliner and the canvas cover.


If it's black mold, it ain't going away period other than removing it
and then using a mold killer.


Mold Killers:

1. Alcohols (ethanol, isopropanol):

Bactericidal, Virucidal, Fungicidal. Use a diluted concentration of 60
to 90%.
Advantages - nonstaining and nonirritating
Disadvantages - inactivated by organic matter, highly flammable

2. Quarternary Ammonium Compounds:

Bactericidal and Virucidal with limited effectiveness, Fungicidal. Use a
diluted concentration of 0.4 to 1.6%.
Advantages - inexpensive
Disadvantages - inactivated by organic matter, limited efficacy

3. Phenolics:

Bactericidal, Virucidal, Fungicidal. Use a diluted concentration of 0.4
to 0.5%.
Advantages - inexpensive, residual
Disadvantages - toxic, irritating, and corrosive

4. Iodophors:

Bactericidal, Virucidal, Fungicidal, Sporicidal and Tuberculocidal if
contact time is for a prolonged period of time. Use a concentration of
75 ppm.
Advantages - stable, residual action
Disadvantages - inactivated by organic matter, expensive

5. Glutaraldehydes:

Bactericidal, Virucidal, Fungicidal, Sporicidal (prolonged contact time
required), and Tuberculocidal. Use a diluted concentration of 2%.
Advantages - unaffected by organics, noncorrosive
Disadvantages - irritating/damaging vapors, highly toxic, expensive

6. Hypochlorites (Chlorox Bleach):

Bactericidal, Virucidal, Fungicidal, Sporicidal (prolonged contact time
required), and Tuberculocidal. Use a diluted concentartion of 1:10 .
Advantages - inexpensive
Disadvantages - bleaching agent, toxic, corrosive, inactivated by
organic matter; removes color from many interior fabrics; dissolves
protein fibers (i.e. wool, silk); has not shown to be effective against
stachybotrys spores.

7. Hydrogen Peroxide:

Bactericidal, Virucidal, Fungicidal, Sporicidal (prolonged contact time
required), and Tuberculocidal. Use a diluted concentration of 3% or greater.
Advantages - Relatively stable
Disadvantages - corrosive, expensive, degrades in heat or UV light
