I use an electric leaf blower to dry. I haven’t tried the $200+ blowers but the leaf blower is cheaper and works well. I’ve used a foam cannon, that works well for dry dirt but some spots still need a little scrubbing. The waterless cleaner is awesome but it takes a bunch of microfiber cloths to make sure the cloth is rolled properly upwards as it is used so each bit of paint only sees clean dust free microfiber. It is great for trips. Some microfiber cloths will have binding on the edge and that binding isn’t as soft as the microfiber. I have self healing Xpel on hood and leading surfaces. When wet washing, I use 2 buckets and I have a piece of plastic light diffuser (used for fluorescent lighting) cut to fit the bottom of each bucket. That white plastic is a grid with ~1/2” (1cm) holes. It sits in the bottom of the bucket and allows grit to settle with the wash cloth kept well off the bottom. I actually use 2 stacked pieces of that plastic grid, it’s cheap. My car is white so doesn’t show every tiny mark as a black car would. I have a California duster but don’t use it. Mine seems infused with wax and makes streaks, not scratches, just wax streaks. I have not tried the distilled water rinse methods, but I might if I had a car show type car.
