it sooner than I can, I would appreciate hearing about it.  
(Suggestions for common sources of lye would be appreciated, also.)

Easy off oven cleaner and drain cleaner are two. I've used it on 
occasion to remove soaked in oil from old military gun stocks when 
refinishing them. 

NaOH will attack the cellulose in the paper. It is pretty nasty 
stuff though. In fact, I belive it will attack all organic material. 
Get it in your eyes and you may not be seeing much of anything ever 
again.  

It also reacts with/etches many metals (plating and anodizing shops 
use it for striping/etching). 

This stuff is a little too caustic for my tastes. I dont like using 
it unless I have to. But then thats just me.
