Chian Cleaner is an active cleaner/degreaser suitable for the chain and drivetrain components. 

Application 

Apply the chain cleaner on the chian, the front and rear derailleurs. Let the cleaner soak in for about 5 minutes then rinse off with soapy water.  Then dry and re-lubricate the chain and drivetrain parts. 

(always re-lubricate the chain after cleaning)
