The Bike Cleaner Concentrate has arrived! That's right; Muc-Off's relentless R&D team made their Nano Tech Bike Cleaner that much better by creating a handy refill pouch! It's the same award-winning cleaner but in concentrate form! Just one 500 ml pouch will make two liter bottles of Nano Tech Bike Cleaner! Or, if you're really into bulk buying, Muc-Off's 5 liter concentrate makes up to 20 bottles of Nano Tech Bike Cleaner! Re-using is even better for the environment than recycling, and that's what makes the Bike Cleaner Concentrate so amazing. Each Bike Cleaner Concentrate pouch uses 89% less packaging than the equivalent two bottles of 1 liter Muc-Off Bike Cleaner. So don't chuck out your old Bike Cleaner bottle; save it and save the planet. It gets even better. The Bike Cleaner concentrate can also be used as a powerful degreaser in its concentrate form and it really works like a charm in Muc-Off's (sold separately) X1 Chain Cleaning Device! How's that for multi-use? In case you were wondering, the Bike Cleaner Concentrate is safe to use on your bike's frame, forks, headsets, shock units, bars, grips, seats, pivot points, rims, wheels, spokes, hubs, disc brakes, suspension parts, gears / sprockets, aluminum, anodized metal, paintwork, chrome, carbon fiber, steel, plastics, composites, decals and rubber.
