Restore chalky exterior surfaces without scrubbing using Southeast Softwash OX-KNOX Brushless Oxidation Remover Concentrate (1 Gallon).
A concentrated exterior cleaning chemical formulated for softwash contractors working on oxidized vinyl siding, metal roofing, aluminum composite panels, and fiber cement board. It is applied to lift chalky oxidation, environmental fallout, soot, and gutter streaking chemically rather than by abrasive scrubbing. Dilution is set by how heavy the soiling is, so a single gallon of concentrate covers a wide range of jobs.
Performance Engineering
- Brushless Chemical Action: Lifts chalky oxidation and fallout without abrasive scrubbing of the substrate.
- Gutter Streak and Soot Removal: Targets black streaking on aluminum gutters and carbon soot deposits.
- Multi-Surface Formulation: Used on vinyl siding, metal roofing, aluminum composite panel, fiber cement board, and painted wood.
- Adjustable Dilution: Light duty at 1:15, medium at 1:10, heavy duty at 1:5, so coverage scales with the job.
- Low-Pressure Application: Applied through a softwash system or low-pressure sprayer, then rinsed top-down.
