This is a great tip. I've been riding my bikes for years and i religiously do this every time i ride. I work way to much to find time to be hand washing and nitpicking probeing and prodeing. I ride every weekend usually saturday's up at 6 am to work on the bikes oil/repair/mix fuel/maintence . . . .then we ride all day get home by 9 pm. After i ride i pressure was the bike at the local self serve car wash. A quick ride home helps blow dry the bikes. I have a garden pump sprayer i keep a supply of WD 40 in it. Purchased by the gallon. I spray front to back side to side under through and around the entire frame, pegs, motor, radiator, shocks, carburator, swingarm, bushings, axle, inner and outer wheel hubs, callipers, chain, sprockets, grab bars, fender stays any and all metal.. It only takes minuetes with the garder pump sprayer. I have use WD in the spray can and after a full day or riding your finger dosen't like it. I usually have 2 bikes to do as i ride with my son who is 17. Then i use tire black in the spray can on all plastics, top as well as under fenders, seat, hand grips. gonna upgrade to a pump sprayer for the tire black as well. Push my bikes in the shop and lock them up. Come back the next day and they look fresh. Many other riders comment on how clean my bikes are and they look like they are low hour machines. The WD keeps all metal from rusting keeps polished parts from oxidizing and after the next ride the dirt just slides off when you pressure wash again.
