It is dry here and I’m always so rushed when doing a hose wash. Have a couple of decon washes I need to do. A general question and a specific one…

G. Any tips for doing a wash with hose/pressure washer in very dry climates?

S. Are those inexpensive inline (with hose) DI(ish) filters any good?*

*Think the city says ~240ppm tds
 
I've adopted Koch Chemie Fse into my routine as a drying aid. It takes care of any recently dried water spots from wash day. It's brutal in CO with the sunshine - even a cold day can be so sunny that things dry quickly.

Our water is ~300 tds. That's why I usually opt for a RW with distilled water. I only use a gallon for my car. I also wait until the driveway is in the shade, which is in the evening.
 
My issue isn't necessarily a dry climate due high humidity, but I do have an issue of no shade around my driveway which leads to similar problems.

Like already mentioned, time of day can be critical, but life doesn't always allow for that. Here are a few things I do.
  • Depending on the position of the sun, I always wash the shaded areas first. This tosses the idea of working top to bottom out the window, but I have found it to greatly reduce water spotting
  • When rinsing I use more of a flood approach to reduce the amount of water splattering onto other areas which will dry and make spots before I get there
  • I accept the fact I'll have light water spotting no matter what and do a wipe down with a QD spray or topper immediately after drying to remove any spots
My biggest issue is with larger vehicles like my wife's SUV. My car is tiny and I can typically get through a bucket wash without having any spotting or drying issues.
 
Our driveway is on the northern side of the house, so there's always sun on it during daylight hours. On days with low humidity, and those days are usually windy, I rinse on the driveway and move inside the garage to wash, and back out to rinse again, then back inside to dry. This isn't ideal as I prefer to wash and rinse in sections, but I don't want to move in and out 4 or 5 times either.

I haven't become the guy who washes his car at night yet, but I have reasonable lighting out the front, and I could make it work.
 
I can only wash on the grass in Summer/Winter i start around 6 at night then onto sundown that's with packing up, The sun still shines onto the left side of the car but I make do and work fast.

Our rain water tank is the only source of water to clean car's it's about 10 PPM.

The dry grass is a pain as when wet sticks to the tyres etc
