Cleaning the rotating mechanics

Today at work I asked a co-worker if he had a good idea how to remove the old grease and dirt of the chain and gears. He told me to get a spraycan of WD40, which is the best according to him.

Maybe some of you can tell me more. Isn't WD40 too aggressive for this job? Is there anything else I should use instead?

Before doing anything like that (no WD-40 is not the best), check your chain wear. No need to clean the chain if it needs to be replaced. For the cassette and chainrings, Simple Green and a brush are fine.

WD40 won't hurt the drivetrain but there are less expensive products that will do as well. You could use kerosene, diesel fuel, or similar solvents. I use mineral spirits that I buy in a one gallon can.
Whatever you use be sure to re-lube the chain with a proper chain lubricant.

And ... of course ... in addition to whatever responses you get here, you may want to search the forum. Chain cleaning, lubrication, and degreasing are really common topics....

FWIW, I use WD-40 to clean/degrease my chain. Works okay for me!

I've cleaned up the bike yesterday and had a look at the mechanics as well. It's hardly been used for the past years, previous owner took great care of it. There's actually nothing wrong with the gearing, so I'm not replacing that (for now ).
So what I just want to do is clean it all up perfectly, and then relube it all.
