"Finally I tried CLR Power Plumber. I was amazed. The drain cleared instantaneously and has been running smoothly for over two weeks. The chemical drain cleaners never cleared my pipes like this and, since there are 15 uses in each can, I get as much clearing power as in seven bottles of chemical cleaners."

"It is a rare thing indeed to find a product that truly works as advertised. My sink drain had come to a total standstill. After 45 minutes of plunging, all I had to show for my effort was a sink full of dirty water and a good sweat. I went out to get a bottle of conventional drain opener, and came across your product CLR Power Plumber- no corrosive chemicals, 15 uses, why not? All it took was one application, and instantly my sink was draining. I was so happy I gave my shower a dose just for good measure. Thank you for this excellent product."
