The plastic is acrylic. It’s soft and will scratch easily. The biggest problem is whatever dust on it scratching before you can remove it.
There are special cleaners and polish for acrylic.
You’re not supposed to use windex or ammonia on it.
Soap and water is safe.
I don’t worry too much about scratching personally. If it does, oh well. I have some spray window cleaner and use that with a microfiber cloth and don’t worry about it.
I have some special Endust that’s for electronics and doesn’t leave a residue but helps with static that I use for cnc dust.
I don’t think the acrylic actually retains much odor though. Febreze would probably be the best bet for odors.
