Keeps the kitchen drain smelling fresh and flowing

I was so glad to find this CLR Clog Preventer. I've been concerned about the drain pipes from the kitchen sink. As hard as you try to stop it, there is always stuff going down the drain. Keeping the pipes treated will really help solve slow draining as well. Glad I found it on Walmart.com when doing my grocery shopping.

Wanted a product that would be easy on our 50 year old cast iron sewer main. Safe to say this stuff works, and results are impressive! Left it in the kitchen, shower, and bathroom sink drains overnight and the next morning, the drain flow was noticeably faster! Very impressed and not a waste to do once or twice a month.
