Love this!

Heard a great deal about this foam and couldn't wait to get my hands on it as it's not easy to get in local stores where I live. Even when winter is gone, that doesn't mean I can't get my car pretty dirty and this foam really lived up to my expectations. Really got it clean and got me doubting if a hand wash was needed. There are lots of foams out there but little actually make a difference and this one is proof that you don't need a really thick foam to have something that actually works. It's cheap to buy but I'm not sure if it's the best value for money. After calculating the PIR, I need 400 ml in my lance. Also heard some good things about UF Snow Foam. Maybe I'll try one of these next time.
Touchless is possible

I’ve had a foam lance for a few years now and been fairly sceptical about the whole thing. Sure, it looks cool, but the performance was disappointing using the typical high st products and I really balked at paying more than a fiver for, let’s be honest, it’s just a bit of soap right?
Wrong.
I have a new car. It’s black. I had a black car before and in the end it looked like a spider had taken drugs and a very small knife on it, which let me to thinking that if you can get as much off as possible before any sponge or mitt goes near it, you must be a good idea.
The bottom line is that you do get what you pay for. BH recommend specific dilution rates which you can probably spend some time calculating and your flow rate, but I experimented and found the best results were half mix half water in a 1l bottle and then fiddle with the mix dial gave some amazing results. Frankly, it’s just not comparable with run of the mill stuff. I found that one coat, and leaving it (or ‘dwell time’) of about 5 mins and a single rinse got rid of almost all the film. Regularly used, you could almost consider not doing a proper wash.
Worth every penny.
Bilt Hamber Snow foam 
by Bob Tongs, 20 Aug 2015
This is the first time I have used snow foam, bought this one because of the efficiency/quality of their wheel cleaning product. I found that the foam didn't stay on my Mercedes for long, probably 2 minutes at most, and didn't foam up like other product video's. After washing residue away followed by a regular wash the paintwork came back ok. I purchased a 5ltr pack, but judging by the small amount used it will last me for ever..If your going to buy this go for the 1ltr bottle. Will probable try "Ultimate" snow foam next time and listen to the people who have tested it.
Which Snowfoam?

I have used a number of Snow Foams over the years in my Karcher HDS Pressure Cleaner,with each and everyone proffessing to be the better than the other! I have most recently tried the latest addition to the Snow Foam products to hit the market and that is the Bilt Hamber Snow Foam. I have to report that it has a very favourable perfumed smell, unlike the "solvent" smelling norm for most other similar products. Bilt Hamber does dissolve most road traffic films and grime but it fails to produce a thick enough foam to dwell on the vehicle for more than 5 minutes. Based on my experience I have to agree with Auto Express and conclude that "Ultimate" Snow Foam is still the best on the market!
