How do I wash the bike?

One thing to remember: The operation of your motorcycle is not affected by its level of cleanliness. However, should you feel the need for clean...

You wash a bike almost just like a car; the biggest difference is that you never want to use anything that'll put water pressure on a bike. A pressure washer (either the small portables or those found at car washes) absolutely will force water past seals and gaskets, which means you'll soon be replacing wheel bearings, steering bearings, and maybe an engine. Pressure from just a normal garden hose (nothing on the end, just open) will also be enough to get past the seals on bearings. So, only use water from a bucket and a sponge or soft microfiber cloth to wash and rinse. You may want to consider two sponges: one for the bodywork and one for the dirtier, grittier areas.

But past that, use the same products for cleaning as you'd use on a car. Never use anything other than a car soap/shampoo, unless you're planning on replacing the wax. Some way of blowing air (compressor, leaf blower, shop vac) will make getting water out from crevices a lot easier and keep water spots from forming.

Also, try your best not to get any fluids on the brake pads. Some simple car shampoos can ruin brake pads when left to sit for a few minutes. The chemicals used on brake pads are rather susceptible to other chemicals.

Recommended cleaners

S100 and P21S are good motorcycle shampoos. You will likely still need to rub things a bit, but not much. Use a wet microfiber towel and let the cleaner do most of the work.
