I have and continue to use socks, but; that does not make it a good idea. I have recently become aware of the harmful effects of silicon on wood stocks. Google that. This is a good question and valid concern. I think there is good cause for doubts. I still use the socks. Those of us who don't actually understand, might want to consider this. My impression is the damage from silicon is real, slow and long term. But, the sad part, I dont know about these socks in any practical terms.
Not knowing is a bummer. It seems we might be better served with some kind of non-petroleum grease or synthetic wax treated sock. Something safe for both wood and steel.
One added line of defense is to put a good wax finish on the wood prior to storage. I hear good thing about Renaissance Wax. Google that.
The socks can breathe, moisture should not be trapped or blocks out. I keep a meter and light bulb in the safe to monitor moisture near 50%. I also have these rechargeable desiccant devices that absorb moisture, change color and then can be plugged in to dry out. I keep a good eye on moisture. The socks prevent dents also keep my finger oil off the metal when moving guns around. I hate to give that up.
