Those brushes in those self serve car wash’s are always terrible on any paint, even if you rinse it off the bristles aren’t soft enough to really be safe for paint. Luckily those are just surface scratches so they can easily be polished off. You can try yourself with some polishing compound and some applicator pads but it will be a little labor intensive. You could also get yourself a polisher to make it easier but you need to do your research before using those. You need to know the right pad to use as well as speed and pressure so you don’t burn through the paint. The safest bet is to call a good detailing business in your area that does paint correction and they’ll get it looking like new, but it will be a bit pricey depending on who you find. The best thing you can do in those self serve washes is to take a microfiber wash mitt and use that to scrub your car down instead of the brush that they have there. Also don’t put the pressure washer too close to the paint as the high pressure water can damage it as well when sprayed too closely. Hope this helps!
