That site gives you as good picture on how to clean your bike the only thing I suggest is save your money on special cleaning fluids and go to your local store and by some orange based solvent and use that to clean. It is multi purpose so you can clean the entire bike and your house (and car if you own one) and it is a fraction of the cost of these bike chain cleaners. Look for the concentrate you may think it is more expensive but it last a heck of of a lot longer than your bike cleaners or pre mixed stuff and is still much cheaper. Do use bike chain lube and boesheild or something like that to oil your moving parts. You can buy the brush kit, but I just went to the dollar store and bought a couple of brushes that work well enough. I do however use a pedro chain cleaning machine, that I found works better than trying to use a regular brush to clean the chain. Don't forget to clean your dérailleur pulleys and cassette.
