Can I just wipe them gently with a damp cloth without damaging them? Probably dusty and smoke coated. HLG.

Agree with @BudgetLED, growing light are using is special environment, to help clear the light now and then can help lengthen the lifespan of the light. and the right way is important.

Is it ok to use rubbing alcohol? that's how i 've been cleaning them between grows. wipe lightly with a micro fiber cloth dampened with the alcohol.

Isopropyl Alcohol is what HLG recommends to use as a solvent, anything other then Isopropyl Alcohol could damage the fixture.

Not sure, I would consult HLG or your light manufacturer about doing anything other then what they recommend.

I refurbish laptops (specifically Dell e6410's) as a hobby and sell them on eBay. These can be trashed and compressed air can be useful for cleaning mother boards when vacuuming alone does not work. While I have access to dried pressure regulated air, those air cans used for keyboard cleaning would work well.
The low pressure that they contain should not hurt a QB but make sure tape or wire nuts don't fly off. Also wait for them to be room temp; the air will be cold and I can see issues occurring if it hits a hot surface.
Microfiber is a much better choice than a paper towel which is known to scratch surfaces especially screens on laptops. I surmise they would be just as abrasive to LEDs. Just watch the loops if the cloth has them so they don't snag and damage anything.
Iso is the go-to for me; just get as high of % of alcohol you can get. Do not get a 50-to-50 ratio of water to alcohol like the cheap crap is. Amazon has 99% for $3 btw.
