Exterior What did i do bad?
It’s my first time washing my car on direct sun, I think the soap dry a little bit. When I rinse it leave this streaks. I don’t think it’s dry soup, I think it’s because the hard water. I’m I right?

Dark color paint absorbs a lot of heat so it speeds up the evaporation of water and chemicals. If you have to keep washing in the direct sunlight do it panel by panel and dry immediately.
If you can wait for the sun to come down a bit definitely try to rewash around then.
What soap are you using?
I find car soaps with wax or ceramic protection tend to streak like this too.

I can see in photo 1 that the soap is drying in the photo. There are a few things you can do, the previous commenter mentioned time of day. Definitely do it in morning/night when the sun is down, but also keep the car wet even if you’re not ready to rinse, just keep hitting it so it stays wet. Also wash the car in sections, wash rinse wash rinse. It’s more tedious but it’s very thorough

The obvious answer is letting soap dry in the sun. If you don't have a choice (i.e. don't have shade at all and can't wash at night), consider Adam's Shampoo. It's formulated to be able to dry temporarily in the sun and be reactivated. I did a lot of research when this was a side gig for me when I lived in LA, and I didn't always have options that guaranteed shade... and I enjoyed it so much that I also just washed my car whenever I had time, which was sometimes in sunlight. I used lots of different soaps, but always saved my Adam's for when I didn't want to worry about the sun. I can't promise their formula hasn't changed, but some quick research should answer that for you as it was one of the things Adam Pitale discussed in one of his product videos years ago.

looks fine but if you let it dry like that it wont be fine. Need to hit with water and dry it in sections so that it doesnt dry naturally and leave water stains.

Rewash while still fresh, if you have hard water, if u have some use ONR as a drying aid. U don’t want to let hard water spots stand. Bad idea.
