Not a huge concern if you go get a roll of clear acetate film...from Hobby Lobby or order on the Internet. Figure out your window size and pre-cut a bunch of sheets of it.

Tape it on to the INSIDE of the glass and tape all the way around it (masking tape) so there are no exposed edges....you're sealing it off to keep dust, etc from getting b/n the acetate and the inside of the glass.

TPTools sometimes includes these w/their cabinets and probably sells it separately but the pre-applied strips of adhesive on their acetate pieces may not completely seal it off.

A lot cheaper to just get a roll and make your own.

I'll try to find the label from a roll I've been using....I think I got this last roll on the Internet instead of Hobby Lobby as it was a slightly thicker acetate.

Sure, it's another maintenance item you have to deal with but arguably a lot easier/cheaper than having to change out the glass itself.

You are supposed to use the clear stick on, window provided with the cabinet and buy, or make as 70 post suggests, replacements when it gets clouded. Gloves wear out/thru too. Like any tool, there is maintenance needed over time. For as little as mine gets used, having bought a pack of 12 several years ago, I still have 7 left.
I, also, removed the fluorescent lamp and installed 2 small size flood lamps in the front, upper corners for light.
