Auto Finesse Avalanche is suitable for use in any foam gun or foam lance system, as long as a final dilution ratio of approximately 100:1 (water:product) can be achieved. With regard to the systems we offer, the following advice applies: (i) for use with a , remove the foam gun body and pour or pump approximately 200 ml of Auto Finesse Avalanche into the bottle, then fill the bottle to the top with hot water, refit the foam gun body and shake the whole unit gently to mix the solution before finally attaching it to your hose - then squeeze the trigger and adjust the top dial on the foam gun body until you get the desired foam thickness; (ii) for use with a , remove the foam lance body and pour or pump approximately 100 ml of Auto Finesse Avalanche into the bottle, then fill the bottle to the top with hot water, refit the foam lance body and shake the whole unit gently to mix the solution before finally attaching it to your pressure washer - then fire the washer up, and adjust the top dial on the foam lance body until you get the desired foam thickness. In both examples given above, you can safely double the amount of Auto Finesse Avalanche used when tackling particularly dirty cars, or else halve it if only a light clean is needed.
