About the F9 Set

Front 9 developed these four high-performance products to handle every type of inorganic stain you'll encounter on restoration jobs. Follow the F9 restoration process to get amazing results.

Double Eagle

Double Eagle is a concentrated, multi-purpose cleaner and degreaser that can also neutralize stains, perfect for acidic stains from batteries, or to neutralize F9 BARC and Efflo. It cuts through oily stains with less dwell time; use it to clean food stains, tire marks, and more. Use on concrete, bricks, pavers, tiles, stone, and more, but avoid asphalt. Perfect for jobs on dumpster pads, loading docks, gas stations, and parking garages. Apply with a pump sprayer or X-Jet applicator. Dilute Double Eagle based on how heavily soiled the job site is. It's biodegradable and safe for most surfaces.

Groundskeeper

Use the F9 Groundskeeper after Double Eagle to keep surfaces looking cleaner, longer. Groundskeeper pulls out caustics in the surface and subsurface levels and brings the pH back towards neutral. This can remove tire marks, soils, and grime. Use on topical stains that have been pre-cleaned, and the stains sit at or beneath the surface of the concrete. Surfaces are easier to clean the next time around, saving you time!

Calcium and Efflorescence Remover

F9 Calcium and Efflorescence Remover is a user friendly, full 31.45% strength muriatic acid replacement. It features a buffered, pleasant smelling acid that has excellent soaping capability for working at lower concentrations. Efflo offers the benefits of a full-strength product while reducing fuming and corrosion.

BARC

Front9 BARC is an orange battery acid and rust remover. Instead of eating away the concrete like other cleaners and causing permanent damage, F9 BARC chemically locks into the concrete reversing 80 - 100% of the stain. It's easy to apply, with no scrubbing or brushing required; you don't even need to mix it. This formula is biodegradable, non-abrasive, and non-flammable.

Pick up the F9 Cookbook to learn all the recipes and dilutions you need for any stain and surface. This set includes 1 gallon of each of the F9 chemicals to restore surfaces to like new.
