Perfect for bike

WD40 comes with me, especially for cleaning of the bicycle used. Sprocket, rear derailleur and crankset incl. Cassette quickly from any dirt and simply removed. Even coarse dirt from the chain can be removed quickly and efficiently.

For those who want to do the same thing on the bike:
Never spray directly on the bicycle parts, but then wipe on a cloth and the parts with cloth or run the chain through the rag. It should be yes only cleaned and degreased not. After that still remember the rites.
Derailleur and rear derailleur are then treated me with Ballistol oil, the chain Finish Line Cross Country.

Also for removing screws etc. vielsietig used. Can not recommend it more.
