Okay, here’s my take on sharing my experience with car wash nozzles for pressure washers, written in a blog-style, conversational tone:

Alright folks, so I finally got around to messing with my pressure washer and car wash setup, and lemme tell ya, it's been a journey. I'm gonna walk you through what I did, what I learned, and what worked (and didn’t!).

First off, I had to figure out what nozzle to even use. I kept hearing about how some nozzles can seriously mess up your car's paint job, and that was NOT something I wanted to risk. I did some digging, and the white nozzle (usually a 40-degree spray) seemed to be the generally agreed-upon safe bet. But I'm the kind of guy who likes to experiment, so I grabbed a few different ones.

• The White (40-degree) Nozzle: Supposedly the safest, we'll see about that.
• The Green (25-degree) Nozzle: For getting a little more focused cleaning power.
• The Soap Nozzle (Usually Black): For applying soap, obviously.

So, the first thing I did was pre-rinse the car. I used the white nozzle for this. Just a nice, wide spray to get all the loose dirt and grime off. I made sure to stand back a bit, not trying to blast anything off with pure pressure. Think gentle shower, not a fire hose.

Next up, it was soap time. I switched to the soap nozzle, filled up my pressure washer's soap dispenser with some car wash soap, and went to town. This was pretty straightforward. The soap nozzle creates a nice, foamy spray that coats the car evenly. I let it sit for a few minutes to loosen up any remaining dirt.

Now, here's where I got a little adventurous. I decided to try the green nozzle for some extra cleaning power on the wheels. I kept the nozzle moving and held it a good distance away from the wheels. It worked pretty well for getting some of the stubborn brake dust off, but I definitely wouldn't use it on the paint – seemed way too risky. I almost used it on the lower panels of the car, but chickened out last minute.

Finally, I rinsed everything off again, going back to the white nozzle. Made sure to get all the soap off, working from the top down. And that was pretty much it! I dried the car with some microfiber towels, and it looked pretty darn good. Not perfect, but way better than before.

What I learned:

• The white nozzle is definitely the way to go for most of the car. It's gentle enough to not damage the paint, but still powerful enough to get the job done.
• The green nozzle can be useful for wheels and maybe really dirty areas, but use it with extreme caution.
• Don't get too close with the pressure washer. Distance is your friend!

Overall, it was a pretty successful car wash. My car is cleaner, I didn't damage anything (thank goodness!), and I learned a few things along the way. Now I just need to figure out how to get rid of those pesky water spots...

Hope this helps you guys out there who are thinking about using a pressure washer to wash your cars! Happy washing!
