This is what I would do. You obviously have other options.
I would find the right sized allen key and remove the acrylic tops. Do not use alcohol at all!! Acrylic cracks when it comes into contact with alcohol. I would use very clean paper towels and have a few dampened with warm distilled water (light microwaving helps). Then I will use dry clean paper towels and wipe the block surfaces properly.
I would lay the blocks and tops on a clean paper towel to dry in a dust free environment (well, relatively speaking). I wouldn't use a hair dryer, but I guess a hair dryer on warm (not hot) heat would work. The important point here is to clean off all possible bacterial growth (if any).
Don't just let the blocks dry without cleaning. That would not help.
I doubt any bacteria would form so quickly, but better to be safe than sorry.
The reason why I brought it up was because your room looks like there's good sunlight. Condensation in that relatively airtight environment plus sunlight just equals mildew and algae growth. That's my experience anyway.
Again, just helping. Comments are friendly and with full respect. Good job with your build.
