Earthworm Drain Cleaner - Drain Deodorizer - Natural and Safer for Families - Six (6) 32 oz Bottles

First, if you are sensitive to strong smells, don't get the scented version. It's very strong. We bought an older house with slow, smelly drains. Every time we ran the dishwasher, it smelled like the sewer was in our kitchen. The bathroom sink gruggled and drained slow, making brushing your teeth quickly an athletic sport. We tried Drain-o and that didn't help. Then I remembered how useful enzymes can be and found this product. We put this stuff down the drain three nights in a row per directions. Smell? Gone! And although the scent is strong, when it dissipated, the smell was still gone. So it isn't just masking it. Slow drain? Nope, no longer. We could run the dishwahser without inviting the sewer into our kitchen. We have tried it on a blocked drain, and it didn't help. But after we used our plumber snake to push the block out, the drain cleaner took care of the smell. I've started buying this stuff in bulk. :-)

Easy to use - it worked to clear a slow drain in the kitchen.

Great product! Keeps my pipes clear.

I've used it as the bottle said, then I've also used it 8 night in a row. And it still didn't work. My household consists of 1 person, regular use of the drains. I used other brand to unclog the drain and it worked well. I do appreciate this product being safe around pets as I have 2 cats, but I'd rather lock the bathroom overnight and use another product than this as this one simply didn't work for me. Now this is my experience, and I see it has worked for other people. Hope it works for you more than me. Also if it doesn't work, you can't return it. So you are stuck with product. I had purchased pack of 6.
