Food grade Caustic soda (lye)

[Jeshmunich]

I have looked and am about to pull my finger nails out!! Does any one out there know where I can buy food grade caustic soda from? Please help.

What do you want it for?

pharma grade might well do the job
from here but never used them.

but if you just want to use it to clean home brew kit, for example, boots, or a decent chemist should sell it. Otherwise wherever you get home brew kit from.
