Wow - this stuff works. I have used it twice over a couple of years and it just. simply. unclogs our shower drain and I recommended to my friend and of course, they love it too.
Great product, tried other drain decloggers and this by far worked the best.
I think this stuff is working however, I really don't know how you would know when you are using it as a maintenance item. I'll let you know!
This is a great product. I have purchased in the past and will continue to do so. This works fast and unclogs grease and hair with ease. I always keep a bottle or two on hand.
Product is easy to use and I feel like it is a preventative step that will help with plumbing. It is not costly and similar items are hard to find in stores. I will continue to use to help prevent build up in pipes.
