Restores chalky vinyl siding, metal roofing, AlucoBond, and hardie board without scrubbing. Rips away fallout, soot, and tiger stripes while remaining vegetation-safe when rinsed properly.
Eliminate oxidation and stubborn industrial soot without abrasive scrubbing using Southeast Softwash OX-KNOX Brushless Oxidation Remover.
Specifically formulated for softwash contractors and exterior cleaning professionals, OX-KNOX is a heavy-duty, biodegradable oxidation remover engineered to reverse severe weather aging and chalking. It chemically penetrates and lifts oxidation, soot, fallout, and gutter tiger-striping from vertical vinyl siding, metal roofs, and architectural panels without requiring exhausting brush labor.
This super-concentrated formula is designed to be diluted based on jobsite severity—a single quart of concentrate can yield up to 4 gallons of ready-to-use solution. When applied with a low-pressure sprayer and thoroughly pressure-rinsed top-down, OX-KNOX restores original surface color and luster while remaining safe for surrounding plants, grass, and painted trim.
