Drano Max Build-Up Remover, Drain Cleaner, Commercial Line, for Kitchen, Toilets, Shower, Sinks, 60 fl oz

This is product is NOT designed to open up clogged drains. It may not even work on most slow drains unless the problem is buildup on the pipes and not a developing clog of hair or similar. I've used products like this before, that are enzymes that break down build up in the pipes. Anybody that has connected a new sink, replaced the drain pipes, or disassembled the drain pipes to find the source of a slow or clogged drain notices the buildup. This will help break that down and prevent it in the future. Armed with those pearls of wisdom, it seems to do what it is supposed to. It's easy to use, much safer to handle than most products that are designed to attack clogs, and it can safely be used on any drain in the house. I'll be buying more of it to use regularly in our frequently-used drains.

I have been using this product once a month for 6 months and no slow drains. I hope it's making a difference.
