Insta-Flo Crystals Drain Cleaner – 2 lb (32 oz)

Works well. Follow the directions. /Try to use when drain is getting slow, before it plugs all the way. Will open drain and keep it open.

I bought this product on the recommendation of my plumber to clear and maintain the 65 year old plumbing I thought I was going to need to replace. It works better than any other product. Follow the directions carefully. Hot water is critical for performance. If it seems not to clear the drain, wait a few minutes then put another couple of cups of hot water in the drain. Totally worth the price.

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.

By far the best drain cleaner ever!

Insta Flo is a great product. It is better than the leading brand. I will purchase this again. I have used the drain cleaner for many years. It is effective almost immediately. You do not need to use a lot.

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

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.

Works well

With the pics provided it seems that you can use this just about anywhere where there’s drainage issue. WRONG …. Seller did not disclose that you cannot use this in garbage disposal, toilet and urinals according to the label … so buy this at your own risk …. For $50+ it’s soooo NOT WORTH IT ….
