Set Up & Maintenance Of Your Snow Foam Lance V2

Our Snow Foam Lance V2 is an indispensable tool for maintaining a swirl-free wash, and it’s now also ideal for applying quick and easy ceramic protection after washing. Designed to work seamlessly with our Avalanche Snow Foam range and Lavish Ceramic Foam, it’s incredibly simple to set up, maintain, and clean when you know the right steps.

Here’s all you need to get started…

How The Foam Lance Actually Works

Snow foam is a two-part solution consisting of a citrus-based cleaner and a foaming agent. When water is forced through your lance at high pressure, it serves two purposes: it creates a siphon effect that draws the product up and out of the bottle to mix with the water through the gauze filter, and it activates the foaming agent, which then produces the foam.

Unboxing Your Foam Lance

To begin using your Foam Lance V2, unpack the contents of the box. It should include:

1x Foam Lance body assembly 1x dip hose and strainer 1x PTFE tape 1x male-male threaded fitting (if applicable) 1x pressure washer adaptor 1x 1.5-litre Foam Lance bottle

Set Up

The main Foam Lance body comes pre-assembled for your convenience, and you will have selected the appropriate adaptor for your pressure washer during the ordering process. Therefore, the first step is to attach the adaptor to the main body of the Foam Lance.

The brass lance body features a female threaded end designed to fit your pressure washer. With the exception of our 1/4 Quick adaptor (which screws directly into the lance using a 14mm spanner), all of our custom adaptors use a smaller 15mm male-male threaded fitting for a secure installation.

First, wrap the supplied PTFE tape around the threads of the male-male fitting. Be sure to wind the tape carefully in a clockwise direction, avoiding any bunching. This will ensure the tape moves with the thread rather than against it when you screw in the fitting.

Start wrapping on the second thread from the end and work your way towards the hexagonal end. A couple of wraps should be enough to create a good seal.

Using PTFE tape in this manner will not only prevent leaks under high pressure but also help the lance sit perfectly straight on your pressure washer.

Now you can screw the male-male fitting into your chosen pressure washer adaptor. Do this by hand making sure that the fitting winds in straight without cross threading.

To tighten your fitting use a 15mm spanner while holding the pressure washer adaptor with a large adjustable spanner (or mole grips). Nip these up tightly.

After installing the fitting into the adaptor, repeat the PTFE tape process on the threads of the other end, then screw it into your Foam Lance body. Be sure to keep the adaptor centered. If the fitting feels loose or is angled, you may need to add a bit more PTFE tape to ensure a snug fit.

Tighten your male-male fitting with a 15mm spanner while holding the body of the foam lance securely. Alternatively, you can use the open end of a 24mm (or adjustable) spanner on the hexagonal part of the Foam Lance for better grip.

The final step is to firmly attach the dip tube to the hose fitting beneath the bottle cap. Your Foam Lance is now ready for use.

Foam Lance In Action

Once connected to your pressure washer gun, our Foam Lance is simple to adjust to suit your needs. Before attaching, however, make sure to add approximately 300ml (about an inch) of Avalanche or Lavish to your bottle, then fill the rest with water.

Screw the bottle onto the Foam Lance body and attach the lance to your pressure washer, ensuring it's fully locked in place. When you first pull the trigger, it's a good idea to spray away from the car for a moment to ensure all fittings are secure.

You can also adjust both the water flow and spray pattern to suit your needs, helping accommodate variations in water flow from your pressure washer or outdoor tap.

The flow adjustment knob is located on top of the body. Turning it clockwise reduces the water flow, while turning it counterclockwise increases it. Keep in mind that less water results in thicker foam, but also uses more product.

To adjust the spray pattern, simply twist the front nozzle from a narrow to wide spray.

Maintaining Your Lance

To avoid dried snow foam residue from clogging the Foam Lance components, we recommend flushing it thoroughly after each use. Start by rinsing out the Foam Lance bottle, then refill it with clean water and reattach it to the lance.

Running water through the Foam Lance will clear out most of the cleaning residues. After cleaning, simply allow your Foam Lance and bottle to dry naturally.

Service & Deep Clean

Periodic servicing, such as deep cleaning and checking for blockages, can be done by partially disassembling the Foam Lance body.

Flushing each part with warm water or a white vinegar solution is an effective way to remove stubborn, dried soap residues. Be sure to focus on the brass body internals, nozzle, plastic strainer at the end of the dip tube, and the gauze filter.

The body can be easily disassembled using basic hand tools to access the gauze filter, which should be cleaned and descaled regularly to maintain optimal performance. This is especially important in areas with hard water.

Removing The Gauze Filter

Once the dip pipe is removed, detach the front part of the adjustment nozzle by gently pressing in the clips on either side. A small screwdriver works best for this—carefully pry them back without applying too much force. Once the clips are released, the front part of the nozzle can be pulled off to reveal the inner nozzle and pin.

Using a small screwdriver or pick, gently push the pin out until it can be removed by hand or with a pair of grips from the opposite side.

Now, you can slide the entire nozzle off.

Gently pry off the front blade holder using a small flat screwdriver.

Use your thumb to roll away the O-ring, exposing the flat part of the body.

Use a 24mm and a 22mm spanner (or adjustable spanners) to unscrew the gauze filter holder.

Use a small screwdriver to push out the gauze. You can then soak it overnight in white vinegar to restore it completely.

Reassembly is the reverse of disassembly. Be sure not to cross-thread or over-tighten any fittings—a simple snug fit will ensure the product remains watertight.
