It's complicated but it's mine #28

My cousin used "Thrift". It is lye based. Like I said it did take two treatments for the sink. You pour in 2 cups and let it sit an hour. On the sink the second time, I did it during the day when no one was home and then I flushed it with hot water after. I can't remember the name of what I bought but it comes as a liquid in a plastic bottle and then it is in a plastic bag. It cost about $8.00. Cheaper than a $40 plumber coming out to estimate.

Worth a shot. Oh and I got mine at Home Depot. The guy said it was the best they had and I had never tried it.
