(New member here, so a formal hello to everyone!)
I just set up my first lye bath after doing the oven cleaner method a couple of times. I found that Lowe's carries "Roebic Crystal Drain Opener" which is 100% pure sodium hydroxide. It was $15.08 for a 2lb bottle. The store nearest to me was out of stock but the next nearest had a whole bunch of it. You can check your local availability online too which is convenient. Hope it helps someone out!
