I've always been a hose and bucket guy, but since getting my Tesla recently I've given the no rinse wash a try. I gotta say I think I may prefer it over the hose and bucket, even on a nice day. One of the benefits of the no rinse that I did not appreciate was that water does not get forced into all the little nooks and crannies, only coming out hours or days later, when you drive the car. As such, there is also less of a probability of leaving enough water behind to freeze the doors and windows. Can also do it in a warm garage without getting much water on the floor. But the best part is since you do one area at a time, you can stop in the middle of the wash without risking water spots. I've even left the buckets out for a day or two and washed individuals panels as they needed it.
If you're wondering how the no rinse wash works... Fill a 5 gallon bucket with warm water, then fill another bucket with two gallons of warm water and add one of the no rinse wash solutions to it. You can use a microfiber towel, wash mitt, or some type of sponge. Dip the wash mitt in the no rinse wash solution, and gently glide it over the paint, doing one section at a time. Start at the top of the car, and work your way down. For example, I'll start with the roof first, and do one half at a time. Then rinse the wash mitt in the clean water bucket to remove the gunk you just removed from your car's paint, squeeze the water out, then toss it in the no rinse solution bucket. Dry the panel you just did. Now take the mitt out of the rinse solution, squeeze some of the water out(I leave it just dripping slightly), and do another panel. repeat till the car is done. I save the dirtiest parts of the car for last.
