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.

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

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.

Use this every month to prevent clogs
I purchased the Drano Max Build Up Remover Drain Clog Remover and Cleaner, 60 oz bottle. I had seriously bad clogs in both my shower/bath drain and my bathroom sink drain. My shower drain was so bad it would fill as if I was drawing a bath. I decided to buy the Draino brand because it has always been around forever and has a well known name. I live in an apartment so I can’t and absolutely won’t use that god awful sulphuric acid because it corrodes your pipes. I did follow all of the instructions, but unfortunately it took more than just one application to get these 2 clogs resolved. In fact for my sink and shower drain I used the entire bottles. Thankfully, I had purchased 2 bottles. The clogs were finally cleared thru completely in about 2-3 days. I guess I better think about putting this on a subscribe and save to use monthly so these clogs don’t continue to happen. I took one star away because using the 1-60 oz bottle did not fix the problem. This might not be the case for others, depending on the drain clog. Otherwise I recommend using this product.

Not meet to expected
I used this product for routine maintenance to prevent kitchen drain clogs, but it was not very effective. Water still drained very slowly, so I ultimately had to switch to a heavy-duty drain powder to get the job done.

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.

WOW!! Clog gone
I recommend this product. I had a clogged toilet. I did the initial step, it worked then. Did the three day steps, WOW!!! The toilet is now working. I'm glad I used this instead of spending $500-$700's on a plumber. There is no bad chemical odor. It's easy to use. I'm keeping this on hand to have my toilet running smoothly. I highly recommend this product. You can't go wrong

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.
