SUN UV OXIDATION: Common surfaces like aluminum or vinyl siding can be damaged by the
UV rays of the sun on the Southern and western exposures on the building. This oxidation
can be easily removed by diluting the appropriate amount of Oxi Wash into water and then
applying and brushing with a truck-wash style bi-directional brush although good results are
often achieved with one application. A second application may be required and additional
brushing may be required. Remember you are trying to remove oxidized paint from the surface
thereby exposing fresher paint beneath the surface, much like compounding the paint
job on a car. In this case you are achieving the results chemically.
METAL CORROSION: Some metals like aluminum naturally leech oxides that cause a black or grey streaking on the aluminum surface or on adjacent surfaces. This is commonly seen on white aluminum gutters and is often described as tiger striping. Another example of where this is often seen is from oxidation leeching from the corners of window casings or out of the weep holes in the bottom of vinyl casement windows. This will often display as a grey streaking that may be confused as mildew streaking or may even remain after the mildew streaking has been cleaned away - exposing the oxidation.
- General Oxidation mix add 32 oz. Oxi Wash to 1 Gallon of Water.
- Bad Oxidation could take as strong as a 50% solution add 1 gallon of Oxi
