Removing mailing label gunk

Hi Manney, I frequently buy books that are discounted or second hand. These always have annoying old labels on them that are a pain to remove. And my goal is to save the books cover at the same time (typically these are the glossy style covers that are popular for computer books these days). What I do is remove the majority of the "gunk" either with my fingernail or carefully with a pocket knife and then I use something with a sticky backing to remove the rest. The material with a sticky backing might be the label I just removed or scotch tape or a new label I've peeled off of some junk mail. You take that stickey material and repeatedly (like 50-60 times), stick it on the gunk and then peel it off again. This is incredibly tedious, but it works like a charm. You end up with a perfectly clean surface with no damage done during the cleaning. This may not work for you epson since you may not be able to reach all the places where there is gunk. But give it a try. Jon
