Hydroxi Pro Carpet Cleaning Crystals combines the cleaning and deodorizing power of Hydrogen peroxide with the anti-resoiling capabilities of a crystalizing polymer. This unique formulation helps reduce contamination associated with indoor pollution without the build-up of sticky residue or high V.O.C. solvents. The result is a process that leaves your carpet cleaner than ever and fights resoiling by encapsulating residual cleaning agents and soils in a hard, brittle polymer. 32 oz bottle. Pack 6. Each case includes 1 - 8 oz measuring cup.
