Griot's Garage Brilliant Finish Foam Cannon

DECODE #6: Griot's Garage Brilliant Finish Foam Cannon

The foam gun, decoded.

LABEL: an attachment, not a washer. It needs a pressure washer — a garden hose won't drive it. Its job is pre-soak, not the wash: foam loosens dirt so the contact wash moves less grit.

CHEMISTRY: the cannon mixes soap with air through a mesh into clinging foam. Foam dwells on paint, giving surfactants time to lift dirt before you touch it. Foam alone doesn't clean — it buys time.

NUMBERS: maker requires at least 1,540 cleaning units (gpm × psi), max 5,000 psi. Jets included: 1.1mm standard, 1.25mm for bigger washers. $19.99 at Blain's ÷ 52 weekly washes ≈ $0.38 per wash in tool cost (estimate, not a printed spec).

FIT: right for pressure-washer owners wanting a safer pre-soak. Skip if you have no pressure washer, or expect foam alone to replace washing. It won't.
