Works well for hair
[This review was collected as part of a promotion.] It seems to break down hair really well. With two girls and myself all with curly thick hair the drains tend to clog quickly. This product is easy to follow the instructions and easy to store away under your sink.

Good for bathrooms
[This review was collected as part of a promotion.] This works well I thought. My husband is not a fan of liquid cleaners like this since we own our home and he worries about it damaging the pipes. But this did clear drains in our bathroom!

Deff worth the hype
[This review was collected as part of a promotion.] Great product, cleaned my drains and got rid of the small “drain flies” I had in my house for days. It has a slightly strong smell but it’s worth it because it actually works. I used it 3 nights in a row in my drains and it seemed to get the job done.

Clears clogs in a timely manner :)
[This review was collected as part of a promotion.] I love this drano, the instructions were clear as to how to use the product so that was very helpful. I found no residue left behind from the product and I actually found the consistency of the product to be nice. It cleared up my hairball problems and plan on using this in the future. It comes in a nice sturdy bottle and stores easily.

Great product
[This review was collected as part of a promotion.] I’m really impressed with the Drano Max Build-Up Remover! I’ve dealt with slow drains and buildup before, and this made a noticeable difference without having to take everything apart or call a plumber. It’s easy to use, and I like that the 60 oz bottle gives you plenty of product for multiple treatments. My drains are flowing much better, and it’s a great product to keep on hand for regular drain maintenance. Definitely worth having under the ...

Didn’t work
[This review was collected as part of a promotion.] It didn’t work, it smells like soap and I was really hopeful that it would but as you can see in the photo the sink is still clogged and nothing is passing through so for me it’s a not a recommendation.

Powerful
[This review was collected as part of a promotion.] I had great success using this product. I’m familiar with some of the other formulas from drano, but this was the first time I used this specific one. Just be sure to follow the directions accurately. After one use my sink worked like brand new.

Great build up cleaner so you don't worry months later on of another build up
[This review was collected as part of a promotion.] Seeing that I had recent clogs in my kitchen sink,I thought it was best to try a Build-up remover. This was my first time using one, so I the formulation & consistency would be thick but surprisingly it wasn't at all, so no clean up was necessary. My drain also needed to be clean since it lead smells out, so why not use it.

A Must-Have For Slow Drains
[This review was collected as part of a promotion.] If you are dealing with sluggish pipes, Drano Max Build-Up Remover is an absolute lifesaver.

What immediately gave me peace of mind is knowing that it is completely safe for septic systems, which can be hard to find in strong drain treatments. It started working quickly right after application. The instructions state to let it sit for six to eight ho...

Keeps your Drains Clear
[This review was collected as part of a promotion.] This definitely helped keep my drains clean from clogging! I actually liked the smell of it too- it smells like a good clean smell. Super easy to use. Since you have to wait some hours before running water, I just used it at night.
