South Florida's been under a "severe drought" warning since last summer, So, that's when I stopped "washing" my R*...
Instead, I went to the "Dollar Store" and got three spray bottles (The kind they sell for spraying plants...) One is set up with 1:100 mix of "Fabuloso Orange" (Cuts grease and smells great!) I adjust the nozzle for spray or straight stream. The other is water for rinsing and the third is a 50/50 mix of water and Mothers® Reflections® Spray Wax (the cheapskate that I am, makes me want to make it last longer...)
I actually use the Mothers almost daily... We've got a lot of ocean salt spray here and I usually "straight stream" the water and mist with Mothers and do a wipe down...
For towels I went to Sam's and bought their "restaurant towel" package... There's about 35 white cotton terry towels in the package for about $15 and after the first wash they're nice and soft... (But, you have to wash them first!) I use four to five towels at a time.
The only time I really "soak" the bike is when I'm going to do the wheels... Then I wet the wheels, spray them with "Tire Bright", give 'em a scrub and flush the heck out of the calipers for the rinse... (The first time I did my wheels I came out an hour later to find all these drip streaks on the whitewalls...

)
As far as the windshield... we've got lots-o-bugs... It's a towel soaked in warm water and laid on the windshield for the time it takes to do the wipe down... Same towels, never rubbed or scrubbed and always a fresh coat of "plastic polish" afterward...
BTW: Daytona Bike week is coming up in March... and so is Florida's "Love Bug" season... I've learned to keep a gallon size Ziploc® baggie in the bags for EVERY time I stop... I usually keep a half dozen wet towels in there.
Here's the deal with Love Bugs... Beside the fact that they stink like "Wet Dog" when you try to wash them off, their innards contain an enzyme that will actually disolve plastic and paint! They swarm twice a year. (March and November) The best way to avoid them (beside not riding in FLA

is to get your riding done before 10 AM and after 8 PM... They love heat, vibration (exhaust noise) and exhaust... Oh, and it's been scientifically proven that the "splat coverage" of a Love-bug is directly proportional to the speed of the impact!
And, one last note: that last thing a Love-bug sees when it hits the windshield is NOT it's behind... It's her boyfriend!
(During the "procreation process", it's the female that does the directional flying while the male is dragged around by his... uh, you-know-whats!)
