Thrift T-600 Odorless Drain Cleaner | Hot Water Activated Drain Cleaner for Small Drains, Grease Traps, Septic Systems & Sewer Lines – 6 Pound Bottle

Okay... the first time I didn't read the directions and thought nope. But my plumber said it is the best for drain clogs. So I read the instructions and yeah! My hot water isn't that hot. I boiled 8 cups of water in my micro (you can use a pot of water) but micro is faster. When I removed the 8-cup bowl from the micro, I added a 4 cup of water to the micro. Then went to my bathroom sink and pored about 4-cups of HOT WATER down the drain. Then I added about 1/2 cup of Thrift. Then I slowly started to pour the hot water down the drain. My plumber did warn me to keep a mask on... and yes very advisable. This worked and I did pore 4-cups of boiling water down the drain again just to make sure there was no residual crude in the drain. My stopper has been cleaned, and the drain was clear. No back up. I will do this every month just to keep it working as it is supposed to. Great product. Dumped enough grocery store and home improvement products down the drain, never worked - - - I had plumbers come back twice a year. But I have a great plumber now in my small town and he was honest and truthful and told me about this product. It will save me on plumber services. Fumes don't expand/explode, but they do rise into the air. Better safe than sorry. Use a mask or cover your nose and mouth with a cloth.

works great. perfect for unclogging drains.

This is the only drain product I have consistent success with. I use it constantly to keep drains running free.

After purchasing this for the third time, I thought it was finally time to share the secret with everyone else. This has gotten me out of jams so many times now with stopped up sinks and most recently with a fully stopped up shower drain. After trying all the store brand drain cleaners and baking soda and vinegar, and using a drain snake, we still couldn’t get the shower to drain. We did 4 days of trial and error waiting on this to come in the mail and nothing else worked. As soon as we used literally less than one cup of thrift plus boiling water, the drain erupted with so much gunk boiling out and immediately the clog was gone. The shower drained so fast and we couldn’t believe it. Once again, saved a $200 plumber call with such a cheap and effective solution. One note - be careful not to breathe this in as the smell and air debris is pretty tough on your nose and throat. While pouring it in, stand as far back as possible and try not to breathe it in. If you have a mask, I’d advise wearing it if you plan to stay in the room while this drain cleaner is working. Overall incredible product that will forever have my loyalty!

Works great at clearing out clogged drains

This drain cleaner is hands-down one of the most effective products I’ve ever used, and I strongly stand behind it. Every clogged or slow-running drain I’ve applied it to has been completely cleared, often faster and more thoroughly than anything else I’ve tried. What really sets it apart is that it doesn’t just punch a hole through the clog—it actively cleans the drain pipes as it works, restoring proper flow instead of leaving buildup behind. The moment hot water touches it, the product activates and begins bubbling aggressively, which is a clear, visible demonstration of its power and effectiveness. It inspires confidence right away, and the results consistently back that up. If you want a drain cleaner that actually works and delivers professional-level performance, I strongly recommend this product.

Had been useful but not clearing as well as I had hoped.

My brother is a plumber and this is what he recommends! Definitely works!! Read the label carefully.
