Zep Drain Defense Pipe Build Up Remover Green 64 oz ZLDC648 | Professional Strength, Liquid Formula

This is a must have item in my house. I bought this after I had my kitchen drain unclogged. No problems since, but I also found that it works great in my A/C drain. No gunk buildup after 2 seasons (which is amazing in Florida), with just a capful in the air-handler drain once a month. A bottle lasts for many, many months. I will never be without a bottle.

I use this once a week in our kitchen drain I make sourdough and discard daily . I try to make sure it does t go down the drain but into the trash . It has nice markings on the side for ease of use .

The worst product I ever used I used a whole bottle and I would not recommend it at all runaway pass it away pass it up. I returned it. I use the whole bottle and it didn’t even work at all. My wife bought a gel bottle of some other Drano stuff and it went down great this stuff is junk. I cannot believe that put their name on it.

Didn't clear my drain. Might be good for regular use to keep drain clear just not for bathrooms drains. Ended up ordering plumpers acid drain cleaner which did the job.

Works well and doesn’t smell horrible like most other drain/pipe cleaners. Easy to use as well. We had issues with small drain gnats but this took care of that problem. We haven’t seen one since we started using this.
