The humidity in your garage will be part of the answer. The strings' pressure on the board are the limit on how much the board can swell upwards with additional moisture content. When the board continues to take on moisture content after hitting this limit, it will start swelling into itself (read, compression ridges). My guess is that with no string load, the board will be free to swell up as much as is wants to, given the available humidity. I see no harm in this, now that you don't have to worry about compression ridges. The rim will be happier as partner to the board (and its expansions), now that it's no longer restrained by the plate.

Hmm....I thought removing the strings had the opposite effect.
I guess it depends on what wanted vs unwanted is. I'd hate to commit to answer because of terminology police.

I have a Steinway M sitting in the garage that had a big mice infestation while stored (on its side) for 10 years in someone's shop. I'd like to take all the strings off and then disinfect the piano inside and out before bringing it inside. I will need to store the piano on its side for maybe 6 months to a year.
My question is: Will storing the Steinway M on its side with no strings on it, potentially be bad for the soundboard or any other part of the piano? I am concerned that removing all that tension from the plate and bridge when I remove the strings may introduce unwanted stresses on the soundboard, while it is stored on its side. Thanks!
