I read quite a few posts where the advice for the best clean of ball swirls is Magic Eraser dabbed in Isocol. Well I gave it a try tonight and it works like magic! A slow and patient process but the results are amazing. In the following shot, I cleaned a small area near the biceps and you can see the difference compared to the forearm.
Well, no excuses now for not having anything to do in my spare time.
