After that a slicing through the seat pillar with a long blade using a Saws-All and pulling the pillar apart bit by bit from within the tube. Lye is my least favorite method. Smiles, MH
Lye is one of those things that should be used only as a last resort. Get it on your skin, and it just feels slick, you wouldn't know it's eating your skin. Fail to neutralize it and you'll probably regret it.
I would think m
uriatic acid would be a less destructive option.
It works pretty quick too.
read about it.
