Update: See this new method for drain cleaning -    • The Drain Weasel Sink Hair Unclog Too...  

I've tried many other drain clog removers before, liquid or gel, and the only one that worked and fixed the problem permanently is the Instant Power Hair Clog Remover. Any one can do it, just pour it down the drain and wait 12-24hrs before flushing with hot water to clear the clog.

Get it at your local supermarket, or on Amazon! https://amzn.to/3d20eTZ
