Griot's Garage Brilliant Finish Foam Cannon

The Brilliant Finish Foam Cannon uses a 1/4-inch quick-connect fitting compatible with most standard consumer pressure washers. It is not M22-threaded · an adapter is required for older M22 lances. Two jets are included: a 1.1 mm orifice for electric pressure washers and a 1.25 mm orifice for gas pressure washers. Community foam-thickness reports are strongest at 2.0+ GPM.

A failure-mode scan of community text and video evidence found two distinct owners noting pickup ball rust (the weighted silicone pickup tube's ball weight may be plain steel rather than 316 stainless), and reports of internal anodized aluminum corrosion after approximately one year of use. No single failure mode reaches the 3-distinct-owner threshold this site uses to flag a documented pattern. Griot's Garage sells a Rebuild Kit with replacement O-rings and a YouTube disassembly guide · annual maintenance is a realistic ownership expectation.

The product listing flags Proposition 65 for this product. For a metal-body foam cannon, this likely reflects trace metal component compliance requirements rather than a use-contact chemical hazard during normal operation. No SDS exists for this tool.

The Amazon listing for Griot's Garage Brilliant Finish Foam Cannon carries a California Prop 65 warning. California requires this warning on a very wide range of manufactured goods — including rubber, vinyl, plastic, and metal automotive parts — whenever trace exposure to any of roughly 900 listed substances (commonly phthalates or heavy metals) is possible, regardless of whether the specific product poses a meaningful health risk. As a passive tool, Griot's Garage Brilliant Finish Foam Cannon has no Safety Data Sheet, so there's no chemistry breakdown to translate beyond that.
