Thrift Marketing IS-200 2LB Insta Drain Cleaner

I have been using this for years it is the only product that really works well. I highly recommend this product.

My landlord is pretty slow to respond and cheap about fixing things, so sometimes it’s easier to do them myself. Having two sinks in my bathroom, it was easy to ignore the clog. I tried a few other cleaners that people swear by - they didn’t do anything. Somehow, force of habit, I used that side of the vanity more than the working one. The water would take an entire day to drain. I must have heard about it on social media, because I searched for it by name. I was skeptical because of other products I’d used and because it only mentioned working on *slow* drains; mine was stopped. I ran some water for a bit before realizing it wasn’t hot yet; I turned it off and ran it until it was hot then switched back. I poured the crystals into the water mixture. It fizzed, which was fun. Nothing happened at first. I did it a few more times and then ran hot water and holy fireballs, the drain runs now!!!! There was no smell, but there were some fumes on the initial run (with the cool water). I’d be careful about having others nearby and maybe cover your face / have ventilation. Highly recommend.

This stuff works great. I had a slow draining tub for years. I’ve tried numerous products and even had a plumber snake the drain, but nothing really helped. I did a couple treatments with this (about a half bottle) with boiling water and I’m impressed. The drain keeps up with the water flow from the shower now and we no longer are ankle deep in water when we are done showering.

This is the best drain cleaner for organic matter. Definitely helps with hair in the drain.

I should have filmed just how fast this stuff works. I've been a believer for several years now. Nothing works faster than Insta Flo. The key is, you need hot water for it to work. So I run hot water in a jug and pour it in the toilet, until it's coming out of the faucet hot. Then let the sink fill up with hot water, what little bit actually drains helps heat up the down tube and p trap. Then pour a couple tablespoons on top of the drain and within seconds, you can hear it eating through the clog. And I mean whiskers and toothpaste and soap. It's 100% effective and never has let me down.

Works like a charm! Be careful when you use it and definitely follow instructions but is a miracle for clogged drains!

I had little faith in this working, but had to give it a try because nothing else was working. My 3 daughters and I have very thick long hair and our shower drains can get REALLY clogged. I followed the VERY EASY directions, and within LESS THAN ONE MINUTE, the water was flowing perfectly. I AM SHOOK. This stuff is so worth the money! You will not regret buying this. It’s INCREDIBLE.

This is the only product I use to unclog my drains. Simple and effective. Cleans drains super fast.Do turn on your fans so as to not breathe in fumes.
