| Martin,change your removal technique,instead of clipping it use a razor saw,by clipping you are in effect pulling part of the plastic away from the sprue,this scars the membrane of the plastic itself thus when sanding it it gets worse.
Also make sure that the file you use is wide enough,try a small warding file finishing off with abrasive paper attached to flat sticks,in other words file the entire area and not just the bump itself.
The problem is that so many different grades of plastic exist,each of which has its very own characteristics,plastic being so soft needs care in handling.
