Keeps Drains Flowing Smoothly and Odor-Free!
I've been very impressed with Drano Max Build Up Remover Drain Cleaner, Enzymes & Probiotics. Unlike harsh chemical drain cleaners, this product uses enzymes and probiotics to break down organic buildup over time, making it a great maintenance solution for keeping drains flowing smoothly. After using it regularly, I noticed slower drains improving and unpleasant drain odors disappearing. It's easy to use, and I like knowing it's working continuously to help prevent future clogs rather than just providing a temporary fix. If you're looking for a simple way to maintain your household drains and reduce buildup before it becomes a major problem, I highly recommend Drano Max Build Up Remover. It's become a regular part of my home maintenance routine.

Good product
There is no strong odor as you use it, very easy followed up with hot water. It works too..cleared the bathroom sink clog.

Don't Buy - Doesn't work
over 2 days (following directions) my sinks have NOT shown any progress. I bought this based on prior reviews and was highly disappointed. Now I am out the money, which wouldn't be a problem if the product actually worked. I used this on 2 sinks * Kitchen sink: I use a drain strainer and NEVER dump food waste down (no garbage disposal). It is a dual sink that connects at the center to drain to 1 pipe. One side works perfectly fine, but the other has a clog that THIS PRODUCT didn't clear. * Bathroom sink: in which I only use to brush teeth and wash face and hands. Both sinks are extremely slow to drain. Do not recommend this product.

Actually Worked
Worked perfectly 👌 Our bathtub drain was not draining the water fast enough and during a shower we would end up standing in a tub full of water. I used this as directed and its like we have a new drain!!! Love it and will definitely keep this on hand for future fixes

Didn’t Work for Tough Clogs
Unfortunately, this didn’t work for me at all. I was dealing with a clogged drain, and it just wasn’t strong enough to make a difference. It might be okay for maintenance or very light buildup, but for anything more serious, you’ll probably need something stronger. The only positive is that it has a pleasant smell, which is rare for drain cleaners. But overall, I wouldn’t rely on this for real clogs.

Helped Keep My Drain Fresh
I started using this as a preventative treatment instead of waiting for a clog. It was easy to pour in, and after a few uses my bathroom drain smelled much fresher. I like that it’s gentle enough for regular maintenance.

cleaned up the worst toilet clog possible
This product is amazing. I left the worst biological mess possible before going to bed (from my body) in my toilet and forgot to flush, and let it dry overnight. 22 hours later, I had to use a garden trowel just to get a tiny bit of water flowing. Put four ounces of this in, let it sit for 8 hours, and these enzymes in this slowly eats away dried ****. After two sessions of that, the toilet is almost back to normal. Two more sessions and it will be as good as new. On a side note, this is why I always insist on a place with at least two bathrooms (thank you God), just in case one goes out for a few days like this.

Para eliminar restos de cabello, papel y jabón del drenaje del sanitario.
Es una chulada de producto. Siguiendo las recomendaciones ayuda a qué el drenaje del sanitario y/o las duchas fluyan mucho mejor, ya que se encarga de descomponer el cabello muerto y los restos de grasa del jabón.
