Once you return, you’ll need to rinse it off, but the bodywork should be substantially cleaner, and importantly comparatively free from dirt and grit, allowing you to finish the job with a cloth and shampoo followed by a coat of wax. Another helpful feature is that most snow foams will gently lubricate the bodywork, meaning that you’re less likely to leave scratches or swirl marks. Although it is on the pricier side of things, we do think it warrants the extra money and well worth the investment. Every snow foam is a little different, but in essence they’re all pH-neutral cleaning solutions that, as the name suggests, will cover your car in a dense white foamy layer. You cover the car from tip to toe – including glass, plastic trim and the wheels – and leave it to do its work. How long depends on the instructions, but is usually somewhere between five and 15 minutes. Enough for a cup of tea, in other words. Pretty much any car shampoo can be used in a pressure washer. We have never come across one that you can’t use in one.
