The best foam lance is the one that fits your pressure washer and makes enough foam to cover the whole car in one pass. For that you need the right adapter for the brand of your washer. Below you will find what to look for and which foam lance suits you.
Foam lance or foam gun: what is the difference?
A foam lance (also called a foam cannon) attaches to a pressure washer. The pressure mixes water with snow foam from the bottle into a thick layer that clings to the paint. A foam gun runs on an ordinary garden hose. That is a fine start without a pressure washer, although the foam gets thicker with the pressure of a washer.
What to look for in a foam lance
Adapter per brand. Every make of pressure washer has its own connection on the gun. Further down you can see which ones we have.
Dosing knob. It sets how much snow foam goes into the water flow.
Bottle. Check the tank size: the D-CON Snow Foam Lance V2 holds 800 ml.
Spray pattern. On a foam cannon you set the nozzle from a narrow jet to a wide fan. Wide covers quickly, narrow works better on sills.
Working pressure. The TORQ Big Mouth is made for washers from 800 to 3,500 PSI.

Each foam lance in short
The TORQ Big Mouth has a rotating nozzle that you set with a flick of the wrist from 0° (concentrated) to 90° (wide).
The D-CON Snow Foam Lance V2 has an 800 ml tank and makes an extra thick, clinging layer of foam. Fill the tank with snow foam and cover the car from bumper to roof. Our pick for most washers.
The D-CON Snubby Foam Cannon Gun has a pistol grip with a 1/4" universal quick-connect and handles up to 344 bar (5000 PSI). Handy for sills and wheel arches.
The Snubby Front Quick Lock Adapter is stainless steel and clicks your foam lance straight onto the Torq Snubby Spray Gun.
The Chemical Guys Foam Gun Adapter joins your foam gun to a standard 3/4 inch garden hose coupling. It also fits the Gilmour Foamaster.
Replacement bottles keep your lance in use. The D-CON bottle holds about 1 litre, a little more than the original 800 ml. The PA bottle screws onto your existing PA Lance Canon a Mousse V2.
