Review: 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.

## Questions & Answers

**Q: Can this be use for the sink bathroom?**
A: Yes. But it took half a bottle. My drain still gurgles a little butot like it did. Maybe I'll have to use the rest of the whole bottle/container.

**Q: Is this just as good as roto rooter's brand?**
A: Yes.  The product work exactly as advertised.

**Q: Does this help kill sewer flies?**
A: I don't know because I don't have sewer flies. This product is not what I expected. It is not used to unclog your drain. It's used to coat your drain after it is unclothed. This is supposed to reduce the chances of it clogging up again.

**Q: Is this safe to use on a quartz bathroom sink?**
A: Great question! While we haven't tested this product on a quartz bathroom sink, we wouldn't recommend using it. Hope this helps! -Alyssa, SC Johnson Consumer Care
