Biodegradable chain degreaser. Highly active cleaner for all drivetrain components, particularly effective against oily and greasy dirt. MOTOREX CHAIN DEGREASER penetrates even the smallest gaps, dries without residue, and is non-corrosive. Application: Spray the cleaner on the chain and derailleur, let it sit for a short time, and depending on the level of dirt, scrub with a brush or cloth. The cleaner is very powerful at degreasing, so the cleaned parts should be lubricated again with MOTOREX CHAINLUBE.
