[pianotech] Music Sorb humidity control

[Richard W. Bushey]

Ryan, and others:

That's pretty much what I thought.  Only in a totally, or at least mostly sealed environment could I see it doing much good at all.  Like Paul mentioned, it may have locations and conditions where it does work, but as a rule, most clients aren't going to keep their pianos enclosed in piano storage containers (which I would imagine helps anyway keeping the piano out of the quickly changing room humidity from drafts, open/closed doors, A/C units, etc).  Most clients would stuff a bag in there, forget about it, keep the lid up, cover off, and steam clean their carpets and wonder why it doesn't work! Oh the humidity!


I did happen to look at their prices and they were asking about $37.50 per kilogram, and they recommended 2 per average piano...then they suggested replacing them yearly.  So, $75 - 80/yr is a good little expense, especially if it works marginally at best.

I would be inclined to say no on this product too, except maybe in special cases such as Paul mentioned.

Thanks for your input.

  MusicSorb is a benign product made of silica that is promoted as offering humidity control for pianos. As far as I can tell there is no scientific data that demonstrates its effectiveness. I used to run a dehumidifier in my shop, and I would empty a gallon of water out of that thing every couple of days even when the humidity was only moderate (55%-65%). If Musicsorb did what it claimed, after several weeks of humid weather the piano would burst apart from the pressure of all those expanded silica pellets!

    To all:

    This question was posted to a Linked-In discussion group and wanted to get some opinions on a product that was suggested. 

    The question was: "Are there any suggestions for moisture control on Grands where no electrical plug exists?"  I would add verticals too.

    The one person who responsed gave a link to a product called Music Sorb. http://www.musicsorbonline.com/
    Has anyone had any experience with it or could give any reasons why it would or would not be effective or practical to use? I would guess IF they worked well at all, they would work best with lids down, covers on piano, undercover/back cover, etc. to help isolate the air space you are trying to control.

    I've seen similar products used in pianos that were designed for gun safes, but was skeptical of whether they were effective or safe to use on pianos. Typically, I had them removed more for fear of either chemicals being emitted from them or mice tearing into them and using the beads for nesting material, etc.

    Thoughts?
