I'm going to caution about pressure washing, as the units vary with their output strength. The stronger the washer, the faster it cleans, the more trouble you can get into with forcing stuff between case splits and seals. You have to be careful where you point the thing and how close you get to specific areas. None of the electrical connectors are water tight, and certainly not pressure tight. Leaving water, chemical, and collected dirt from the bike on these terminals, promotes corrosion and future electrical problems. Bar controls don't respond well the pressure washers, for example.
Another example: pressure washing a drive chain forces water into the links and pins and washes away lube. If it's a hot day, you can spin the chain on the bike to centrifuge the water out and then relube. If it was an oring chain the pressure can replace the lube behind the orings with water, and the chain will wear out far sooner, as you can't put lube back in under pressure.
If you are going to use power tools, you should understand what they are capable of doing before using them inappropriately. Yes, I use a pressure washer on my bikes occasionally. But, I know what and where to point it. And I know how close to get the nozzle it to the subject.
Best not to look down the barrel of a gun and pull the trigger to find out what happens.
Cheers,
