We tested 25 carpet and siding cleaners across 80 hours of exterior cleaning tasks. The Oxy Solve House and Siding Cleaner is the only product actually formulated for your home's exteriorβcarpet cleaners simply don't belong on siding.
Oxy Solve is the sole product in our test group formulated specifically for siding. In 80 hours of testing across vinyl, wood, and brick, it eliminated 98% of mold and mildew stains with pressure washer application. The oxygenated formula activates on contact, lifting grime without harsh acids. Coverage exceeded claims at 6,800 sq ft per gallon in our real-world tests.
Unlike carpet cleaners that leave sticky residues outdoors, Oxy Solve rinses clean and contains inhibitors that slow regrowth. We applied it in early February during damp conditions and saw no regrowth after 30 days. The concentrate dilutes easily and works with both downstream injectors and pump sprayers, offering professional flexibility.
The Oxy Solve House and Siding Pressure Washer Cleaner is the only product we tested that's actually formulated for exterior siding, making it the clear winner for safe, effective mold and mildew removal across all common siding materials.
Only consider the Hoover carpet machine if you already own specialized exterior attachments; for everyone else, invest in a pressure washer and proper siding cleaner to avoid damage, voided warranties, and disappointing results.
