It is a good product. Sometimes it works miracles on clogged sinks. Everything seems so expensive with some places ready to gouge us. I would like to see everything be a little less expensive, because it adds up over time.

After trying a couple of different chemical drain openers and still struggling with a very slow draining bath tub, I found this and decided to try it. Instructions for use are super simple. Worked like a charm!

The CLR product helps clear blocked up plumbing lines when other methods do not work. They are especially handy when working on an older house where the existing piping can be delicate due to age.
