Car air freshener inside a console TV?

[MRX37]

The RCA CTC 120 console I got for free is serving me well. There's just one annoying issue: It sat in a moldy basement for maybe 10 years, and within 5 minutes of it being in my room, the smell of mold became very strong.

I've cleaned both the outside and the inside with bleach, and that's helped. However when the TV runs and gets warm, the smell comes back, though not as strong now.

Finally I just bought an air freshener normally meant for a car. I put a small screw in the ceiling of the TV and tied the air freshener to it, then put the back cover back on it. My idea seems to be working. I just wonder if there's any unforseen dangers? The air freshener won't be falling onto the chassis board. Even if it did, it's just a piece of scented cardboard.
