Thrift T-100 Alkaline Based 1-Pound Granular Drain Cleaner (2-(Pack))

This is the best drain cleaner I’ve tried. My kitchen sink was very slow to drain and nothing seemed to help. I tried multiple products and noticed no significant improvement. I tried this product before contacting a plumber and am so glad I did. Within 5 minutes the drain was open and draining normally. The product is easy to use. I used very hot water with it and the drain cleared almost immediately. I didn’t notice any overwhelming odor. You just need to be careful to avoid getting it on your skin. Definitely recommend!

I don't normally get emotionally attached to drain cleaner, but here we are. We have a house full of ladies, which means every drain eventually decides it's opening a hair salon instead of draining water. I've tried the usual liquid products, snakes, and enough hot water to make tea for the neighborhood. Then I found this stuff. First, a word of caution: do not stand over the drain and take a deep breath after pouring it in. I made that mistake exactly once. Let's just say it rebooted my operating system and rearranged a few childhood memories. That said... this stuff is the real deal. It absolutely annihilated whatever biological engineering project was living in my pipes. Drains that were slowly gurgling their last breath are now flowing like they were installed yesterday. Showers, sinks—everything is back to factory settings. This stuff works! Use common sense, wear gloves, give it the respect it deserves, and let chemistry do its thing. Five stars. Would absolutely buy again. Just not because I plan on smelling it twice.

Great product for the price, but be very careful using this product, extreme caution.

My mom actually brought some over after a plumber recommended. I drug my feet on using it, but was instantly converted and bought my own. Its incredibly satisfying to use, and you are not left wondering whether it made a difference. Unbelievably effective, even on old stubborn nastiness. Couldn't recommend more highly.

This is excellent to clear clogged drains! I now keep on hand for slow running drains. Add a half bottle and it clears immediately. Plumber told me about this product!

Best foaming drain cleaner out there just add hot water

We discovered this product on a professional plumbing call at my parents (they have septic). We have used it in 2 different homes with sewer. It’s worked well in all 3 locations!

Works really well!
