Stupid question, but can a dryer damage LS?

it is a somewhat stupid question, but my action through which this comes about is still a lot more crazy. actually, my interior is not only wet, but NASS, and I would like to get a professional dryer from the construction industry. since I have nothing more to worry about than my radio and my LS, I want to make sure here again: is there any danger for radio, soft, LS, blablabla when the dryer sucks everything completely dry inside? at what temperature? naturen such a thing works, I don’t know, but I read something of 30 degrees. laughs at me, instructs me…I know, the question is crazy, but I don’t want to ruin myself any more…
