The pre wash
We supply the popular current Karcher K Series, Gerni/Alto/Nilfisk Pro/Kew and Stihl pressure washer adapters to hook your pressure washer up to the Snow Blow Cannon. If you require a different type of adapter, please contact us as we also keep the more popular Kranzle, Lavor, Karcher HD/HDS, Nilfisk and Kew quick connect, Black and Decker, Ryobi, Bosch and a 1/4" quick connect fittings in stock too.
A lot of these fittings will work on other machines as well (there are literally hundreds of different machines) but if we don't have the fitting you need, they can usually be found online at different eBay stores.
For first time use, screw the required adapter on very tight to the white thread taped end. We have found the base model Karcher K Series pressure washers don't allow the Cannon to swivel and sit straight, so apply some extra thread tape to the connector end and move to where it feels comfortable.
Set up your pressure washer directly in front of your car and connect the power and your hose/water to it. Don’t turn it on yet!
We use a 9:1 ratio of water to foam wash and have made this super easy to work out. Simply fill the Cannon’s bottle to the “Fill Water to Here” mark (that’s 900ml of water), and then top it up with the Snow Job foam formula to the “Fill Snow Job to Here” mark (100ml of Snow Job). We put the Snow Job in last so it doesn’t foam up while you’re filling.
If you're not using our Snow Blow Cannon, each capful of Snow Job is 50mls, so two capfuls is all you need to make up to one litre.
Before you begin foaming away, make sure the car is cool to touch (especially black plastic mirrors and trim) and it's not overly windy. We also think it's best to foam in the cooler parts of the day, like first up in the morning or late in the afternoon. All these are done to slow down the evaporation time of the foam, so it gets optimum dwell time.
Attach the bottle to the Cannon’s screw in intake, being careful to not cross-thread it, then shake it well with your thumb over the adapter tip to stop it splashing out. Now attach the Cannon to the pressure washer, turn on the water, and then power it up.
For the thickest foam possible, turn the Cannon’s top blue air adjustment knob clockwise towards the “-” symbol. If you desire less foam or wish to use less foam solution, turn it the opposite way towards the “+” symbol.
Squeeze the trigger of your pressure washer till the foam starts coming out.
Adjust the Cannon’s blue end nozzle to find your desired foam arc. We like it around half to two thirds the way between full fan and powerful jet.
Keep the Cannon about a metre away from the cars surface to cover it in a lovely, thick foam. Starting on the lower sections and rear of the car, working your way around the car, from the bottom to the top, allowing the foam a longer dwell time on the dirtier lower areas. Let the foam sit and do its work for 4 to 5 minutes, gently dissolving the grit and dirt from the surface.
Remove the Snow Blow Cannon attachment and apply your pressure washer nozzle. Pressure wash the whole car starting from the top and working to the bottom, cleaning the very back of the car last so the foam has the longest dwell time on it.
Don’t let the jet of water get too close to window and door rubber seals or other delicate parts like fabric tops, or emblems on the car. A distance of 30 to 50cm away is always recommended so no damage can occur from the water jet.
Once the foam is completely washed off, use your best judgement on whether it now needs a hand wash or not.
Inspect the cars surface at the rear and lower parts of the car closely for any dirt or grime. If you see any, or if it has been through rain since the last wash, you should follow up this foam wash with a safe two bucket wash method. This is where you have 1 bucket that is filled with our lubricating Nanolicious Wash (best, most lubricating), Wax Wash or Auto Body Gel, and a 2nd bucket that's filled with clean water to rinse your Shagtastic Wash Pad out in each time you come off the car, so you're releasing any left-over dirt and grime from the cleaning tools and never putting dirty water back on the car.
If there was only light dust or sea spray on the car, we find the Snow Job foam can remove it all, so you can begin drying it with The Big Green Sucker microfibre drying towel and the Boss Gloss spray as the lubricant/drying aid spray.
If you don’t use all the foam solution in one wash, it can be stored in the Cannon’s bottle for up to a month.
Use the Fully Slick protective spray as a standalone sealant after the car is all done, as the slick and slippery finish allows the Snow Job foam to be more effective as the dirt cannot stick as well to the slick surfaces. You'll also notice how it also makes the foam slide off the car a bit faster, helping take any dust and grime away with it.
