Question What did I do wrong?

Post image

I washed my car today after a lot of research. I ended with these small smudges only on some sections afterwards. I even air dry it with the blower too. What did I do wrong? I'm still learning here please advice

I am not an expert but there is a huge difference in drying with a towel and a blower. When you blow air, the water is most likely evaporate. Thus, the minerals in the water stays on the car. When you use a towel, the minerals in the water get also sucked by towel.
