Now that you have scrubbed, it is time to remove all that crud. Using a lint free towel, wipe all that black nastiness off the chain and the sprocket. I start with behind the sprocket (picture 1) *Notice the difference in picture 2 once I wipe all that grime off how clean the chain is-red arrow dirty, black arrow clean!
* Picture 3 shows the underside of the chain again. Make sure you are rotating the wheel to ensure you are getting the entire chain in both areas. Also, make sure you wipe down the sprocket teeth.
But be careful! If you turn the wheel too fast you and/or your shop rag will end up between the teeth and chain!
Turn the wheel and listen to your sprocket. If you still hear little chunks of sand grinding between the metals, repeat the WD-40 process until you don't hear it any more. Rest assured this can take at least an hour depending upon how dirty your chain is and how long it's been since it has been cleaned.
