Problem areas like chain guides, hubs, silencer tip, pipe, etc. are scrubbed clean the old fashioned way, with spray bottle and brush. Chains are a special problem themselves, as they tend to accumulate a combination of dirt and lube that is impervious to near all cleaners. What this essentially leaves is scrubbing the chain with a stiff, plastic bristled brush while using ordinary bike cleaner, and rinsing carefully. With all of the above completed, a final power rinse should clean off any remaining dirt, dirt residue and stains. During the final rinse be sure not to overlook cleaning out radiators, handlebars and controls, sprockets, tires, and beneath the fuel cell.
Many mechanics also like to include air box maintenance with their regular cleaning regimen.
If so, the seat is removed, air filter removed and an air boot cover fitted in its place so that the airbox may be washed and hosed just the same as the rest of the bike. Set the air filter aside for cleaning later. CRC helps trouble spots like the pipe and frame rails. Open up the mag cover to allow any accumulated moisture here to dry out too. If you are really into cosmetics, plastic treatments like Armor All will renew plastic sheen, however avoid the seat cover if you intend on riding the bike anytime soon.
