F9 Knockdown

About F9 Knockdown Low-Foam Cleaner, Degreaser & Neutralizer

F9 Knockdown is a professional-grade surface cleaner and degreaser designed for high-traffic, heavy-soiled environments — including parking garages, gas stations, airports, and vehicle service areas. This low-foaming, water-based formula is built to handle oil, hydrocarbons, tire marks, and general surface buildup with ease. It also serves as a powerful neutralizer for battery acid stains and other stubborn contaminants. 

Though extremely strong, F9 Knockdown remains safe for use by professionals: it’s non-flammable, phosphate-free, contains no VOCs or chlorinated solvents, and is fully biodegradable. The low-foam design makes it ideal for ride-on scrubbers, reclaim systems, or standard pressure-wash setups where suds are a concern.
