Thrift T-100 Alkaline Based 1-Pound Granular Drain Cleaner,Red

This stuff is amazing. Had a grease build up in the drain and it cleared it immediately

Amazing product! Works within minutes and helps maintain drains. Highly recommend!

Last year I had a plumber come out for various reasons and he had this and used it to clear out my tub drain. IT IS AMAZING! He told me to check on Amazon and I could use it myself. Never had an reason to until I bathed my 2 dogs and stopped up the drain, lol. I'm SO glad he recommended it! Worked like a charm and water is flowing great again.

Love it! Took care of my bathtub drainage fast. A friend told me about this and it sure does work. Thank you so much.

As always I am skeptical. I used another professional clog remover with nothing happening. This product showed up and I got the area prepped for use. It called for hot water, so I microwaved 4 cups of water. I put 1 cup of the crystals down the sink and poured 2 cups of hot water over it. I waited 2 minutes and then poured the other 2 cups of hot water in the sink. I watched the air bubbles come up and about 3 minutes later a big bubble came up and the drain was emptied. I started to turn the faucet on slowly and then fully. The drain was completely draining and in full use as I let the faucet run for 3-5 minutes. This Thrift product is FANTASTIC!! I will definitely be using this product if my drain gets clogged up again. Well worth the $15!

This seems to work better than the liquid drain cleaners, and it works quickly. One star deducted for size of container. You're supposed to use one cup per treatment, but after you use two cups, there's not enough left for a 3rd treatment, so you only get two and a half treatments, requiring you to buy another bottle.

I live in a house built in the late 1800s. I have ongoing issues with drains draining slowly. I used this in both my kitchen drain and bathroom drain and the results were immediate and wonderful. Both drains now drain normally! The big namebrand liquid drain cleaners did not work nearly as well as this. Just make sure you follow the safety instructions.

I waited a month before I sang this product's praises, just in case it was a fluke. I've had an issue with my kitchen sink for over a year; it always gets backed up, and not at the elbow. It's in the pipes just under the floor. I knew the outside street drain wasn't clogged because I put a camera through it and saw nothing, so that told me the problem was between my sink and somewhere before it hits the main pipe. After a year, my only options were to call a plumber and spend a fortune. Essentially, I would have to connect a hose using a bladder, crawl under the sink, and stuff it in there. I'd run the hose at full blast for about 10 minutes, and it would clear up for a week or so. Eventually, it would start backing up again every couple of weeks. I found this product on Amazon while looking for a drain snake and looked it up on YouTube. Almost everyone put it directly in the sink itself. I knew my problem was in the lower pipe, about two feet down from under the sink. So, what I did was I removed the elbow and the connecting pipe to the main pipe just below the sink that went straight down and made sure there was no water. Then, I poured half a bottle of this stuff in there and put it all back together. They said it reacts to hot water, so I had four pots of boiling hot water ready to go on the stove and poured them in one by one with gloves on. The first time I poured it in, I could hear a loud suction noise as the crystals started to activate. After that, I just kept pouring water in, about three to four gallons, maybe more. I even had the hot water kettle on repeat for a bit. After I finished, it ran clear—but it's done that before, so I waited day after day, expecting it to return. It never did. I said if it's clear after a month, I'll write a review. In my case, I had to put it deeper down in the pipe than the elbow because I knew the reaction to hot water was instant, and I didn't know how far it would go before it became diluted or lost its efficacy. This works and saved me hundreds of dollars. A $15 bottle of Crazy Crystals.

Highly recommended product compared to liquid chemical alternatives. Works much better.

Drain cleaner is very good.. Made light work of a shower drain at my son’s university dormitory accommodation.. Drain was blocked from previous tenants and students over the years.. Cleared it with one application.

Came across this product on social media and have been dealing with a slow draining bathtub for the last few weeks, gave this a shot vs calling up the landlord to assist. Followed instructions and incredibly my bathtub be draining again! Just be mindful to wear gloves, goggles, mask when using as a precaution. Will definitely use again for any stubborn drains.

My washbasin was clogged a lot. The drain cleaner works as advertised. Just pour boiling hot water to activate the process. The situation is clear now.

Great product, there is enough to do a couple small drains in the bottle. Product works fast on most drains, some stubborn ones needed a second run through.
