FAQs

How does CLR Clog-Free Drain work?

CLR Clog-Free Drain is a compressed gas. When the formula in the can is released and comes in contact with water in your drain, it expands rapidly, creating a standing wave. It uses the water in your pipe as a battering ram pushing the blockage through and cleaning the walls of your pipes.

How many applications are in a can?

There are up to 15 applications in one 4.5 oz. can of CLR Clog-Free Drain. Do not hold down can for more than 1 second. If you push down longer then less will be available for use.

What kind of clog will CLR Clog-Free Drain work on?

CLR Clog-Free Drain will work on any clog, including hair, grease, food particles and soap build-up.
