I never seem to get my chain clean enough.
So Id like to hear different ways to clean a chain.


Don't worry if the outside of the chain isn't shiny clean. What matters
is keeping dirt and grit from getting inside the chain where you can't
see it.

The only really effective way to clean a chain is to remove it, and
agitate it in a solvent such as mineral spirits. Then allow it to dry
completely, and lubricate with oil.

I thought the latest "science" was that cleaning a chain didn't affect
lifetime. I've stopped cleaning mine.
