Potasium Hydroxide

[bandit354]

What drain cleaner has potasium hydroxide as it only ingredient. Going to try it over baking soda as I am only using 316 stainless steel in my generator and getting alot of red liquid in my generator. Was told it is the baking soda degrading.

You can probably find it locally, but you can also get it here: http://wardsci.com/product.asp?pn=IG0015473

Potassium hydroxide (KOH) can also be purchased from:

As a side note, Bob Boyce has stated that baking soda over time becomes NaOH (sodium hydroxide), which is highly caustic. I don't remember all the details, but I think that happens after iron is leeched/released or something like that. He states very strongly that baking soda will destroy even 316L SS. However, KOH/NaOH seems to not degrade even 302/304 SS switch plates. I use KOH.
