I wish I had more time to type but here are my recommendations.

Each bucket should get a grit guard but if you only want to buy one, put it in the clean water bucket. You can run the mitt across the guard to remove some soiling.

I usually clean the wheels first with a myriad of brushes to get every part of the wheel. I like to rinse the wheels first before putting on the cleaning product. Some disagree with this approach since it can dilute the product but when I clean wheels, lubrication is key IMO. Dry + dirt = scratches. My raw aluminum CCWs still look great using this method.

I use a soap gun before I start cleaning the car with the mitt. It adds some extra lubrication to the surface to avoid scratching.

I'm decently quick working my way around the car but if its a hot day, I will rinse off each area after cleaning. Top to bottom is a nice approach but also consider ending with the front and back since those tend to get dirty the most.

When drying the car, I actually use a little bit of spray wax on each panel. It adds some extra slickness and I think it dries better. Waffle weave microfiber drying towels work the best IMO. I use two with one being used to get the big water off the car and the 2nd is the finisher.

Separate microfiber towels are used for the wheels. Same process and I use spray detailer on those as well. If I have the time, I will get the compressed air out and blow the water out of the crevices before the final dry. Nothing bothers me more than drip lines after a good wash.

I then open the doors, trunk and hood to wipe down those areas. It only takes a few extra minutes and really cuts down on the time I would need to spend if i let these areas get really dirty.

You choice in car wash is fine. The more suds the better IMO. What mitt are you using?
