Best Foam Cannon: Reviewed and Ranked

A foam cannon attaches to a pressure washer and blankets the car in thick, clinging suds that loosen dirt before a wash mitt ever touches the paint — the closer to a touchless pre-wash you can get, the fewer swirls you put in. Pull it out for the weekly maintenance wash or when the car's been sitting through pollen season. Not strictly necessary if you do a careful two-bucket wash, but it's the single biggest upgrade for swirl-free results. Needs a pressure washer to work; a foam gun is the garden-hose alternative.
