    I thought maybe vinegar (acetic acid) might be safer to neutralize the lye, but apparently that is not so good, either. Apparently copious amounts of water is recommended to dilute the caustic, and then vinegar for final clean-up.

    I work in waste water. Dumping lye down the drain to a sewer system is not bad. We always have a problem with low pH not high and use a lot of it to correct the pH. We call it Caustic and it is EXTREMELY dangerous for your eyes! It will dissolve them in an instant.

    Boy, there's a lot of armchair chemistry on this thread. (Not you, Dan.)

    For just a little more, you can do it yourself!

    Does your county not have a household Hazmat day, when you can dispose of pool chemical, paint, solvents, etc. at no cost?

    Have you tried peeing on it?

    You should have a great command of Ralph Norton quotes and jokes at the ready. But he was quite an artist and these days it would be lost on all but a few old timers.

    One plant I have been working at has a female operator who was pregnant. Her husband was an oprator there too. I said to her “I know what that kids first word will be. Poop!”
