I'd try Zaino Z5 first. It is non-abrasive and will not remove any clear coat.
I got some swirls on my old sparking graphite E90 after the guys at the touchless wash place used towels to dry my car (what the xxxx????). One coat of Z5, applied by hand, took care of business. It also adds a rather good shine. If a couple of coats of Z5 don't work, I'd try Z-AIO or Z-PC, both of which are somewhat abrasive.
