Amazon Basics Max Strength Drain Cleaner Hair Clog Remover Gel - Unclogs Hair and Grease, 80 Fl Oz, Packaging May Vary

I've three times used concentrated sulfuric acid to unclog drains; the smell is awful, pollutes the entire home and even the outdoors as it goes out the vent pipes. I decided to try this as it's super concentrated bleach and lye plus some fragrances. My shower had been twice reamed out by roto-ripoff and flow problems came back. Once again, I was standing in water over my ankles after a shower which took 2 hours to drain down. With 3" 60 year old drains, I poured most of the bottle in, about 4/5th, zero odor (thankfully) and let it sit for 2 hours. Afterwards, there was no accumulation of waste water in the drain even with the handheld sprayer removed for maximum flow - it sold me! Price is right too, and it didn't eat the chrome off the drain like sulfuric acid does. Great product!

I was plesently surprised as to how well this worked, on slow drains to a bathroom sink and shower. It's an Amazon 'basics' version so it's cheaper than the name brands, but it works as good as any of them. Nice big jug too, so it lasts awhile. I highly recommed this.

Impressive drain clog remover. Good price. My only suggestion is that a clear panel is needed on one of the narrow sides of the container so that you can see when "one-fifth" of the bottle has been dispensed. One-fifth of the contents is the recommended dose for clogs and you have to measure this by heft. If the weight feels like 80% of what it was before it was opened, then you've used one-fifth of th contents. Kind of imprecise and this makes it easy to use too little of too much when seeking to unclog the drain.

I’ve never had much luck with draini or other drain cleaners but I’ve been able to unclog several drains with this. I have bought it a couple times and now I know to grab an extra when I order, just so I have one on hand when I need it. I’m very pleased. It does smell like bleach, so open a window when you use it.

I used this to unclog my sink before, and it worked in no time. This time, my bathtub was really clogged—it took hours for the water to drain every time I took a shower. I tried this twice first, but it didn’t work, and I was about to give up. On my third try, I boiled a kettle of hot water (note: water that’s too hot can actually damage the pipes), and then it worked! It! Worked! It really saved me a huge hassle, and I’ll definitely keep buying this product.

I have pets and my washing machine drain will clog up if I don’t use a drain cleaner monthly. This drain cleaner is much less expensive than what I used and works well at removing hair from the drain line. I use an automotive funnel that has a long flexible tube attached to pour the drain cleaner into. All my other drains work well and I normally treat them every six months to prevent clogging. Using the Amazon basics drain cleaner is saving me a lot of money.

This entire jug didn't accomplish what one very small bottle of green gobbler concentrated did in an hour.

Works just like drano! On my first attempt, the shower was still clogged. I read another review where the user poured hot water from the kettle after leaving the product in. I tried this and it worked! I know we need to be careful with hot water so let it cool a little after warming it.
