Snow foam is a great and effective way to deep clean your car.
It breaks down dirt and oils and I'm not sure there is a more effective form of pre-washing when it comes to keeping your car shiny.
But which pressure washer should you get to give you that magical cleaning power?
There are plenty of options out there, so I've personally tested, reviewed and compared the best options available in the UK so you don't have to. I've linked each one via Amazon so you can order yours today, but many of them are also available fromHalfordstheB&Q.
The Paxcess pressure washer is everything you want from a pressure washer if you want to clean your car. It has good power at 135 bar, but not so much that it will damage your paintwork in any way.
The snow foam lance is easy to attach and set up, and while I wish it came with some detergent, you can buy your own easily enough (polar blast is a great option if you come across it).
You'll also love the quick-connect nozzles that adjust the angle of the spray, giving you from a tight jet for stubborn dirt to a wide jet for general cleaning and soap removal. Nothing beats trying to wash away soap scum with a narrow jet, so this is very handy.
You get an 8m hose and an 8m power cord with it which for most people allows them to easily run it from their house. But even if you need an extension cord, the machine itself is lightweight and on wheels so you can move it around easily.
In total,If you are interested in a thorough car cleaning and need a snow foam cannon, the Paxcess is the pressure washer for you.
2. Runner Up – Pro-Kleen 1600W Jet Washer with Snow Foam & Detergent
- Comes with detergent and cloth
- Great for details
- Durably constructed with aluminum components that will not rust
- The pipe could be longer than 5 meters
This is the pressure washer you have ready for car washing, it has the snow foam adapter as well as 5 liters of detergent so you can unpack it and start cleaning. Plus you get some microfiber cloths for a deeper polish and finish.
You get similar cleaning power to the Paxcess above with the same pressure, a little less electrical power, but you also have 3 meters less hose.
Now, this can be good or bad.
If your hose is close to your car, it's great because you have less hose to arrange and store and less chance of kinks. But for many people, this is not enough and you will have to get an extra tube to cover the distance. That's what put it in second place.
It's an easy fix and I love the unpack and go approach you can take with it, giving you effective cleaning power in the most convenient way possible.
3. Best Karcher – Kärcher K3 Home Pressure Washer
- Integrated detergent tank
- Trusted brand
- 6m pipe
- Many accessories available
- Includes patio cleaner
- Snow lance sold separately
- Car wash not included
I couldn't find a snow foam set as part of a karcher deal, the FJ6 foam nozzle is always sold separately,and sold here on Amazon.
But this German engineering is hard to beat and combine the FJ6 part with the power and price of the K3 and you're on to a winner! I went for the K3 because it has good power, but not so much that you risk accidentally damaging the paint or tires.
Plus you get the Vario lance which adds cleaning power by spinning the water as it exits the lance adding agitation to the mix and providing a deeper, more thorough clean.
The K4 also comes with patio cleaner and patio cleaning detergent for a total package that's as effective as a home pressure washer. As the name suggests…
You can trust a Karcher and this is the best choice when it comes to using a snow foam attachment.
4. Budget Choice – Wilks-USA RX510 Pressure Washer
- Snow foam included
- Includes patio cleaner and brush
- Under £100
- Shorter pipe length 5m
- Do not use a brush in your car
Wilks USA is probably best known for themgasoline pressure washerbut their electric does a great job too, and it's a great price to match.
What's disappointing, apart from the shorter length of the tube similar to the Pro Clean, is that the brush attachment doesn't do well with cars. If you are very careful and kind and only use it in your car, it is fine. But if you use it on your patio, wash it off, and then use it on your car, you're likely to get it covered in scratches.
But the snow lance works well to get a solid coverage of soap and the regular lance gun works really well at washing them off again.
So as with anything on a budget you get what you pay for so if you can I would spend a bit more and get the Paxcess, you get a better pressure washer and a better clean.
5. Best Multi-Purpose – Power Pressure Washer with Patio Cleaner
- Pipe length 9.7 meters
- Lots of accessories
- Includes swivel cord for extra cleaning power
- The hose connector is not the best
- It feels a little weak
Now if you read this is a steam pressure washer then you did exactly what I did! The brand is Stream and they have made a great multi-purpose pressure washer.
He has the bottle of snow foam, which of course is why we're all here. It has a nice long hose that you will enjoy and of course, you have all the accessories needed to clean the house. A patio cleaner, a brush, the snow foam, a lance, a rotating head for extra cleaning power and the jet stream for super stubborn dirt.
If you're after something multipurpose, then this is just the ticket for you.
The only problem is that many people report that the hose connector has a tendency to pop. Not something I experienced, but as one reviewer says, you can easily fix this with some PTFE tape that will hold it in place better.
It would be nice if things just worked, but when you're spending less than £200 on a pressure washer, you just have to roll with the punches.
Snow Foam Pressure Washer Buyer's Guide
If you don't like any of the recommendations I made, then fair enough! I won't hold it against you and I still want you to find the right one that you need, so here are some general considerations for buying a snow foam pressure washer.
It comes with the attachment
First of all, does the pressure washer you are looking at come with a snow foam gun? It's not a standard accessory and if it doesn't come with one, you'll need to purchase it separately.
But what's not obvious is that you'll want to check if this brand makes their own or if you're going to need to buy a third-party attachment.
And if you prefer a different brand, then you'll want to make sure it connects. Some pressure washer models have a Karcher attachment so you can attach Karcher accessories for example. Something to think about for sure.
What other attachments do you need?
If you just plan to use the pressure washer to wash your car, then you can use the snow gun. Other than that, you'll just use the normal lance attachment to wash and clean the car.
But you might consider some microfiber cloths or possibly a buffing mitt to help get that extra shine to the finish.
If you want a more general purpose pressure washer, you might consider something for cleaning your porch, maybe some other type of brush for scrubbing work or windows.
You can buy most of these separately but if you like attachments then Karcher is the way to go, they have the biggest range of them.
Should you pressure wash before foaming snow?
Yes, it's a good idea to get the car wet before you snow foam, and a good idea to remove any hard bits of dirt that may be on it. Give the car a good spray and worst then go in with the snow foam for a deeper clean.
Washing off the snow foam?
You definitely want to wash off the snow foam right away so you don't have streaks left over afterwards. I guess you could hope it rains, but that's probably not a good idea…
Do you need to scrub after using a foam cannon?
No, the foam cannon removes much more dirt than regular soap, so generally no scrubbing is required. If you wanted to, you could rub it but you really don't need to.
What PSI is safe for car washing?
You generally want to keep it at or below 2000 PSI which is about 137 Bar, which you'll notice is right around the power of all the pressure washers I've talked about here!
This covers just about everything you could hope to know about buying a pressure washer with a snow foam gun attachment.
Bet you didn't know there were so many!
And luckily the next fun step is to hold it in your hands and clean your car. Because using a snow gun is surprisingly rewarding. I'm sure there are women who love to use them, but I know it satisfies my husband's brain by covering my car nicely in foam.
SNOW FOAM TOP TIPS
Water Supply – The pressure washer should be rated 1,800 psi to 3,200 psi and at least 1.75 gpm flow for optimal foam production and application. If the water supply is insufficient, it can starve the pressure washer, resulting in poor snow foam production. Be sure the supply hose isn't kinked.
