Simply spray-on and rinse off: Fenwicks Fast Blast Degreaser is an easily applied and super efficient drivetrain cleaner.
Coming in a handy aerosol, Fast Blast gets to work straight away at dislodging the nastiest bits of road gunk off your drivetrain - just spray, wait 30 seconds, rinse and repeat until clean.
Road grime starts to dissolve immediately, and with a bit of agitation from an old tooth-brush chain-rings, mechs and chains are brought back to shiny life again. I, uh, deliberately, let my drive-train get extra manky to see how the spray coped, and it took two applications to get it looking smart again - about par for the course.
As with any spray it's easy to get carried away with applying it, but with restraint it's an effective and good value cleaner - just make sure you've got something underneath to catch the crud.
Easily applied, good value drive-train cleaner, capable of clearing out the most severe of road gunk.
