Cleaning Bike Chain

1) Remove the chain.
2) Take the chain to a well-ventilated or outdoor area.
3) Pour an inch or so of solvent, such as Gunk degreaser or Simple Green, in a small pan or basin.
4) Soak the chain in the solvent.
5) After a minute or two, take the chain out of the solvent and scrub with a course brush. 
6) Put the chain back in the solvent, or if the solvent is too dirty, discard it in a safe manner and add new solvent.
7) After another minute, remove the chain, wipe with a rag and dry.
8) Repeat as many times as necessary.
9) Be sure to remove all the solvent before you put the chain back on your bike.
