RCP's Pressure Washer Foam Cannon is a must-have for laying down a thick, clinging layer of foam during a routine maintenance wash or a pre-wash before clay bar decontamination. Rated for a min-max pressure of 870-3190 PSI, a flow of 2.6-5.3 GPM, and a max temperature of 140 degrees F, it is built to pair with a wide range of pressure washers for serious foaming power. We recommend filling it with your favorite car wash soap and adjusting the dilution to dial in the perfect suds for everything from light maintenance to especially dirty vehicles. The thick foam helps encapsulate and lift dirt for a safer, more thorough wash. This foam cannon paired with a quality pressure washer, a wash pad, and a plush drying towel will take your detailing experience to the next level.
