    I did this pretty often… and it clogged my drain. My plumber told me to quit it. The baking soda didn’t all dissolve and turned into a hard mess. I still use boiling water occasionally or some bleach. Someone told me that the septic system enzyme granules work well without damaging the pipes, but I haven’t tried it. Now we have a hair screen and a sticker with the plumber’s number in the vanity. My clog was always too low for the drain claw type things, and I am not good enough with a snake to work it myself.

      Sorry you didn’t have any luck with the baking soda and vinegar. Thankfully, it’s always worked for me, so I’m not keeping my plumber in business! No matter what drain clogging method you use, the hair screen is a huge help.

      Thanks for the tip! My husband’s always complaining about my hair clogging the shower drain, so we finally added a “hair trap” that we have to clean out every couple of days!
