Insta-Flo Crystals Drain Cleaner – 1 lb (16 oz)

Really recommend this product. Works great and clears tough clogs fast.

I ordered this based off the recommendation of a maintenance man I know. Had issues with our bathroom sink suffering from slow draining. Used this product and it quickly cleared the drain. Very fast acting, no noticeable odor. Great value for the money.

Best thing on the market to clear a drain. Follow the directions.

If you have bio-matter (hair) in your drain, this stuff is a MUST HAVE! It works very well! I now use this stuff about 1-2x per year...if a drain even looks like it's starting to drain slow.

Like other people, I've wasted hundreds of dollars on drano etc... and nothing works like this stuff! I will only buy this product from now on. I am ordering my second bottle now because my drain is old and really stubborn. I have long hair as well as two of my dogs that I bath in the shower. With the first bottle I just emptied, I used one cup to begin with like the directions say, and immediately, like others have said, you can hear it burning the hair and also hear the small swish sound of the drain clearing. So for me, it worked about 75% with the first bottle. But like I said, I won't use anything else as this works above and beyond any others! And again, my drain is extra tortured from all our hair, so I would need the most powerful cleaner in the world, and so far, this stuff is the closest to it! Tips I agree with others on that now I know to do with my second bottle: wear gloves! I didn't and like others, it itched and burned my skin on my hands and up my arms. I didn't even touch it at all. It was the fumes alone. So when using it, wash your hands and arms with warm water and dish soap frequently and you'll be fine. Also, just use the hot shower water to warm the line in the beginning, but after that, once you shove the flakes down the drain, heat up water, I did in the microwave till scolding hot, and when you want to add a little water to the flakes, use the scolding water. You will hear more burning the hotter the water is! Brilliant!

SO HAPPY. I have been without a draining shower for two weeks now, and this stuff actually worked when nothing else did. My grandmother suggested it - both their house and my apartment were built in the 1920s, (two states away), and we’ve both had a lot of issues with funky drains. My shower drain has been slowing down quite a lot, until it was barely budging. Both my teen and I have long, thick curly hair; despite using two drain traps and snaking about once a quarter, it always seems to get clogged. (I think it’s a mixture of hair that still gets through and the oils in the conditioner we have to use for our dry curls! IFYKYK.) It’s backed up before in the past three years. and I was usually able to eventually clear it with very hot water and vinegar. Last time my landlord used a plumber, so I tried it this time. Nope, that was worse. It made it go from barely draining to refusing to budge. I eventually had to keep scooping the water out with a cup, and resorted to washing my hair and briefly the rest of me over a bucket like I did in the field. 🫠 So I was cautiously tried this today; it took almost the entire bottle, which I poured in about 1/4 cup at a time. I couldn’t really flush the pipes with hot water since it was trapped all the way to the drain, but I did try to run hot water for about 20 seconds before turning the water off and pouring in the first round. At first it didn’t seem to work, and I noticed the stopper engaged to plug the tub - had to keep an eye on it and disengage it three times. After about 30 minutes and a final almost boiling hot water flush, it is a full blown whirlpool of draining. I could cry. Wish I hadn’t already washed my hair over a bucket, so excited to take a full shower tomorrow!!! Highly recommend, 10/10.

This stuff works great! Little to know older, works on the clock right away. If you use it regularly. Drain will stay clear.

Had a plumber recommend this product and it works amazingly. Use it mainly on my bathroom sinks and showers. It is so fast working and a lot cheaper than a plumber

Un trop cher mais ça fait bien le travail merci beaucoup et je le recommande à tous
