Another trick a professional plumber told me about was to run very hot water for a while, giving it a couple minutes to drain out & then adding the acid. Supposedly helps it work much better.
It says on the bottle not to use hot water.......but I remember the old timer that told me about this stuff to use it with the hot. I did use hot first then drained a bunch out through one of the clean-outs in the basement. Then I poured in the acid, let it sit for 20 minutes and rinsed with the cold. It drained. Then I filled the sink with hot water and drained twice.
