Oh thanks! I'm planning on it. Right now I'm trying to find lye at walmart. Looks like all the drain cleaners have moved to something else.

Try a hardware store. Lowes carries NaOH, so if you've a lowes near you.

I'm in Mexico and have yet to find a lowes. But they do have home depot. Going there now.

I live in mexico too. Homedepot had it last time we needed it for cleaning.
