Where to get Lye, Caustic Soda or NaOH
 

I need a source for 100% Lye in Calgary. Seems all the drain cleaners out there are some concoction of something or other. I need this so I can regenerate my GFO. Anyone know of a chemical supplier that could sell me some?

Look for places that sell soap making supplies. They use lye for making soap.

Cheers,
Vic

If you know anyone in the well drilling business they could get you some.

You can buy pure lye from home hardware in large containers(1 gallon milk jug roughly). I think it is arond 20$. At least the home hardware here has it.

You can also recharge di resin with that stuff, tried looking for those things briefly today but no luck.
