Yours looks pretty clean to me. The yellow and white is the hardest to get clean and yours has minimal ball swirls.
Best tool I've found is Magic Eraser with isopropal alcohol. Go slow and be prepared to stop is the paint gets thin. DO NOT scrub continuously in one spot or you WILL wear through the paint. Make sure to wipe off all the residue before it dries or your will have to use magic eraser again to get it off.
