Gorilla XDX features an nature friendly formula that blasts through oil stains without the use of acids or caustics. This biodegradable, non-flammable product removes petroleum based soil from concrete without scrubbing. Gorilla XDX breaks down the oil?s Hydrocarbon chain with a unique combination of high grade surfactants and oil Eating bacteria. Usage: wet method where rinsing is available: attach a spray top (pump sprayers may also be used) and adjust it to a heavy mist. When dry, rinse with a bucket of water, hose, or pressure Washer. Gorilla xdx will not interfere with oil separators. Dry method where rinsing is prohibited: attach a spray top (pump sprayers may also be used) and adjust it to a heavy mist. Spray directly on dirty gas pads particularly on heavy oil spots. Gorilla xdx will gradually break down the Hydrocarbon chain and dissipate the oil without rinsing or scrubbing. For immediate results, apply and wipe clean with an absorbent pad or a cloth. Agitating with a deck Brush will also speed up the process. Unlike bio-organic dry powders, gorilla xdx can be used in damp or wet conditions and will not leave a gummy residue that gets tracked into the stores.
