At Muc-Off, we're big into being active. Whether it's on a mountain, trail, or at the skate park, we just love to be outside and going big. Bike Drivetrain Cleaner is the complete drivetrain cleaning solution. Spray it directly onto your chain rings, rear cassettes and derailleurs, or use it with a chain cleaning device. It cuts through grime, dirt and oil in seconds, removing all chain oil and wax residue. It's biodegradable* and safe for metal, plastic, rubber and seals. You have never seen results like this — we can guarantee it. Dry bike chain lube is a highly versatile, dry weather chain oil that has state-of-the-art penetrative qualities to ensure that the lube is driven deep into each chain link's core. It uses a wax-based formula to protect against contaminants in dry and dusty conditions, reduces friction and provides smooth, quiet gear shifting. It's biodegradable*, PTFE-free, and safe for you, your bike and the planet. Both products are part of Muc-Off's Project Green, we love the planet we ride on, it's our playground, and we're driven to protect it for everyone.. How to use—shake the bottle vigorously and spray all over the drivetrain, including the cassette, chainrings, chain, and derailleurs. Leave for up to one minute and agitate with a brush if needed. If using a chain cleaning device, remove the trigger sprayer and fill the device with the formula. Rinse thoroughly with water to remove all residue. Once the drivetrain is clean and dry, apply a moderate amount of Bio Dry Chain Lube to the inside of the chain while pedaling in a reverse motion, then wipe off any excess with a microfibre cloth.
