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. I was dealing with a frustratingly slow drain, and this formula took care of it without hassle. 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.

Easy to use, works as advertised
[This review was collected as part of a promotion.] It is easy to use, a great alternative to snaking the drain. It cleared the clog I had and didn’t leave any residue or require any clean up after. It works as advertised.

Great in the bathroom!
[This review was collected as part of a promotion.] It was thinner than I expected it to be, but we thought it worked great! We used it in our kitchen and bathroom sinks. Helped with the drainage, especially needed it in our bathroom! We have already bought another bottle. The scent was pleasant for a chemical.

Great for clearing and maintaining drains
[This review was collected as part of a promotion.] I’ve been really happy with the Drano Max Build up Remover. It’s easy to use and has helped keep my kitchen and bathroom drains flowing smoothly without much effort. I like that it’s designed for regular build up and maintenance rather than only being used when a drain is completely clogged. The 60 oz bottle is a good size, and the liquid is simple to pour and use. Overall, it’s a convenient product to have around and has worked well for keepin...

No harsh fumes
[This review was collected as part of a promotion.] So I used this product on my toilet as directed for 3 days. I noticed that the water flowed much faster than before. I love that is is also safe to use on septic tanks! It has no harsh fume smell at all. I’ve used this brand to help with clogs. This one is slightly different as it doesn’t unclog the pipe but eats away at the buildup on the pipes that happen over time.

Works really well!
[This review was collected as part of a promotion.] This drano worked really well! I have a sink that is constantly getting clogged/drains slowly and after using it there was a noticeable difference immediately! The smell is nice and not too much like chemicals. It didn’t require much to clean my sink, too! Highly recommend.

Works great
[This review was collected as part of a promotion.] I like the consistency. It wasn't thin to where I felt it was just wasted, but not too thick. It was really easy to use and effective in unclogging my sink. The scent was pleasant.

Sink draining much faster now.
[This review was collected as part of a promotion.] I am pretty pleased with this product. For a few months now our bathroom sink has been slower than usual. I have only used this drano max build up remover once, but I can tell already that it has made a difference. I really like how thick the liquid is so it sticks to all the built- up goo that was building up in my drain. My drain is drained much quicker. I am pleased with this product and would recommend

Great clog remover
[This review was collected as part of a promotion.] This train now works very good at unclogging stock drains! I only had to use a very small amount. The instructions were clear and it didn’t smell offensive either which is a huge plus.
