All of Fenwick's range of cleaners are very environmentally friendly and kind to your hands, and the FS10 bike cleaner is no exception. Marketed as an 'everyday cleanser' for your bike it's helpful when it comes to getting the general road grime off your steed, but no more so than a bit of washing up liquid, really, and it struggles with sterner tests.
Juice Lubes' Dirt Juice is a very powerful degreaser and bike cleaner and the twin pack is pretty good value as well. You'll need to be a bit careful with it in its concentrated form but it does a super job of removing even the thickest grub from chains and mechs.
The twin pack gets you a litre of Dirt Juice Super Gnarl - the strong stuff - and a litre of Less Gnarl which is the same product diluted ten times. The two bottles come with a single spray head which you'll need to swap between them for different jobs but that's not a big deal.
Nothing comes for free and to get the best from this spray you will need to roll up your sleeves, fill the wash bucket and get your bike in showroom condition. Once you can see your face reflected in the rims, apply a generous coating of Muc-off Bike Spray over the whole thing.
