Weldtite Snow Foam Bike Cleaner
500ml £10.49
Weldtite’s Snow Foam Bike Cleaner is an aerosol spray that coats the whole bike in foam, which can, handily in some circumstances be removed without water. A candy floss scent makes a change Oxford’s mint and various citrus effects from a variety of manufacturers. I’d like to say that I’d prefer toffee apple, but that would be unfair and flippant and might antagonise fans of vanilla.
Pros: surprisingly frugal for an aerosol, effective without water.
Cons: nothing significant.
Specification and science
As I have already stated, this is an aerosol spray. That may put some off on eco grounds. As you’d expect there’s between 5% and 15% propellant, which include hydrocarbons. Needless to say, this makes it combustible, so take the usual precautions that you would with any aerosol. Less than 5% is anionic surfactant, important to reduce surface tension and make it easier to life dirt form your bike. The rest is, well, the cleaning agent. Note, you’ll need a proper chain cleaner or degreaser for the drive train.
Weldtite state that the spray is good for all surfaces, including rubber, carbon, disc brakes, bar tape, et al, however, if you have particularly fancy finishes or precious components, e.g. leather bar tape, you may want to check it out first. Importantly, it is safe on e.bikes.
On the can it says “for frames, bars, wheels & pedals.” No mention of saddles. More of that below.
Weldtite promise a controlled and accurate application, and point out that this can be used with either a pre-wash or final rinse with water. Waterless washes can be especially helpful in certain circumstances and can be quicker and more convenient if time is pressing. Indeed, e.bikers may feel this could be a plus, too.

Application 3.75/5
The instructions are simple; spray the foam all over the bike, leave if for a minute, and then wipe it off with brush, cloth, or rinse with water. Simples, no?
Well, very much simples, yes! With less propellant and surfactant in the mix than its sibling Thunder Foam Degreaser, the foam is thinner and less prone to bulking up. Snow Foam is an appropriate name; it put me in mind in the kind of spray-on artificial snow one might use for Christmas decorations. True, one can lay it on thick – and this is intended to be used as a foam and not a liquid – but it is easier to get a suitable, evenly spread layer.


Frame and forks were easily and accurately covered without much waste. Likewise, tyres, although spokes and carrier struts required a wipe to get full coverage. I covered a battery powered rear light mounted on the mudguard, too. There seemed to be no ill-effects – but it is a very well-made light.
There’s no need to agitate with a brush – you can do this when brushing away the foam or wiping with a cloth. Water from a garden hose or a watering can has the same effect. Weldtite say leave it for a minute, but I have not seen any ill-effects from leaving it longer, nor any great advantage (even in really filthy nooks and crannies. Best not let it dry on the bike, and it will slowly evaporate (not hat I have noticed any harm).
Performance 3.5/5
First up for a dose of the Snow Foam was of my Surly LHT. The period since its last clean had been unusually dry for an English spring, so there was a good covering of dusty, dry over the whole bike. In addition, there was the odd spot of chain lube on the chain stays.
I decided, for the purpose of testing things out to clean the bike in two parts: front and forks; and rear and stays. Having covered the front section in foam, I used a brush and a cloth to wipe away the foam. With a dry cloth and a clean brush, the foam came away with the dirt leaving a clean bike and clean rims and tyre walls (A tyre scrub brush is useful for the tread). All pretty well smear free, although Weldtite recommend use of their own silicone protect and polish or its carbon equivalent to put a shine on. Certainly, using a brush and cloth with a bit of care, got dirt out of those places where either the sun don’t shine don’t shine or it rarely gets a look in. By the way, I was doing this with the wheels on, because it is quicker and I was feeling lazy; however, it does make for a realistic post ride clean, if not the full monty.
Front half efficiently done, time to spray the back. All done and minute or so counted down, out came the watering can for a good sloosh down. Given that a cold-water rinse generally leaves things looking impressive, this looked good. As ever a wipe with a clean cloth helped to remove any bits that had been missed. Overall, the two methods of getting the foam and dirt off appeared to make little difference.



Dry weather dust sent on its way with ease, I needed some real muck to get to work on. Fortunately (I may be alone in thinking that), the dry weather broke to be replaced by bands of rain followed by intermittent showers (typical early spring weather in the UK) set in. So, a dose of rain, I duly set off for my favourite country lane where water tends to stay longer and Daisy the Cow and her friends always add to the fun. I timed my ride so that she and the herd would have returned to the fields following morning milking. The Snow Foam made a good job of lifting this fresh much during a post-ride wash. However, personally, I would go for a sudsy bucket washes such as Crankalicious Mud Honey for attacking filthy MTBs, Cyclo-cross machines, or ingrained dirt on neglected winter utility bikes (like mine).
Friendly to all surfaces, as far as I can see, although I have kept it away from leather saddles (there are better ways of cleaning and nourishing those). On gel saddles and others it has left things clean and shiny.
The waterless approach might appeal when at a trail head and wanting to load the bike into the back of a vehicle, or when avoiding polluting a watercourse. It is also that bit quicker when no initial rinse is needed. The latter is true of Blub Bike Cleaner, but that does like a rinse off to get the dirt off. You don’t even need that with the Snow Foam.
Value 3.75/5
Muc-Off’s Waterless Wash comes in around the same price. It’s a pump action spray, but is probably more frugal – less propellant and more product – even at £17 for 750ml. In my opinion, on dirt lifting, although it is a close thing, but the Muc-Off tends to leave an even better finish. Tru Tension Snow Foam is also £10 for 500ml. Again, another waterless wash that's designed for convenience. I've found it works well, but you've got to get busy with the cloths quickly to avoid streaking and watermarks.
Summary
Make no bones about it, Weldtite Snow Foam is an effective bike cleaner. Yes, yes, yes, it is a competitive field, but if cleanliness does not stand head and shoulders above the field, it does not mean it is not very good. It may be of particular interest to those who want a quick and easy, and potentially waterless cleaner; at the trail-head, in the car park, if you are short on time, or frequently cleans lightly soiled bikes.
Verdict 3.75/5 Handy addition, especially to your trail-head kit.
