Dust has started to become a problem with my display case. I don't have time to regularly dust it, and the way it was built it comes with two window panes so there is a 3mm wide split in the middle. Anyway I closed that split with a strip of plexiglass, and it is a mighty fine job, it doesn't detract from the display at all, and it's a pretty tight fit. Problem with dust - solved. Now, another problem has cropped up. The place that I bought the plexiglass from kept it who knows were, so it has a strange smell that maybe borders on the stale. It's not obnoxious or anything like it, it's just kinda weird. The problem is the whole display case smells like it when I open it. The smell goes away after 10-15 minutes, but it picks up the smell again after I close. How do I fix this? Would it be a smart idea to get those car fragrance dispensers in a small can and put it in the display case? Or maybe open up and put a pack of baking soda on each shelf?
