By this time the rag and your hands should be all gunked up with black crud.
Spray anything that moves or pivots on the bike with the Wd-40. Brakes, brake levers, shift levers, cables, everything. Dont spray the tires or rims though. Try to get a little in the cable housing anyplace there is an opening. Wipe everything down with a clean rag.
Next give the tubes a shot of spray furniture polish. Buff it up with a clean rag.
Is WD40 a good idea on a bike?
