I recently just bought an open box unit online with a broken front tempered glass door. I can definitely say it is not worth it. I’m about five hours in tearing it apart only and I haven’t even started cleaning it up yet.

It is practically impossible to get it perfectly, clean realistically. Think of it like you’re cleaning up sand inside your car. You can clean as much as you want, but overtime you’ll keep seeing glass all over the place even though you thoroughly cleaned it. All the glass shards will practically get into all the holes and crevices inside the machine.

I definitely think it’s not worth it since glass will also get into your lead screws, causing it to grind on the screw and damage it over time. You can clean the lead screw as much as you want, but due to the crevice picking up glass and getting it stuck there, you won’t be able to clean it without replacing the whole lead screws.

The biggest hazard isn’t only getting cut by the tiny shards. It’s also breathing in the tiny glass particles and can damage your lungs. If you’re fortunate enough to have a large compressor to blow air into all the nooks and crannies it will definitely help but make sure you wear a mask. That’s at least KN95 that’s designed for painting cars.
