I would do a waterless wash, they work awesome. It's my preferred wash if it's not too dirty (like with heavy salt or heavy mud).

Get two buckets and put grit guards in each. These help trap the dirt at the bottom of the bucket.

Get a few microfiber towels for washing (an old rag will do for the wheels)

Then these waffle ones for drying.

It'll take you 15-20 mins tops. Just fill one bucket with water, one with soap and water. Go out to a dry and dirty car, dip a towel in the soap, do a panel then dip in the water and ring it out, back to the soap and repeat. If it's super sunny I'd dry as you go, otherwise you can do the whole car before drying.
