I take issue with this description.. If you use a MRP guide, they recommend against using anything citrus related to clean your chain. Also, if you lube your chain directly after cleaning it, the cleaning agent will immediately begin breaking down the lube you just applied. Truthfully you DO NOT need to buy any fancy cleaners or bike-specific products. I use a light mixture of of a soft soap like dish washing liquid over most of the bike. IF my gears and chain are gunked up badly, they get completely removed and cleaned with a hard cleaner like Simple Green, then they completely dry before going back on and getting lubed.
