Bioda BEB-00013 Drain Cleaner & Odor Eliminator, Professional Strength, 1-Gallon

it works well to open up and improve drain flow by using digestive enzymes to break down waste. I used a different product in the past and this one seems to work just as well. works a bit slower than a standard drain opener but removes any odors as well and maintains the pipes when used regularly.

This product seems to do the work. I had bad smells coming from my drain pipes in the bathroom sink and tub. Directions followed, and the drain smells seemed to dissipate after a couple of days without using the sink and tub. I followed the instructions for a second round, letting the product remain in the drains, without usage, for just a little longer (3 days) to help clean the drains and completely get rid of drain smell. I am waiting for the results. I gave this product 5 stars, because it reduced the drains smell drastically with the first usage.

Easy to use and effective. The liquid removed the odor that I wasn’t able to remove from other cleaning products for my main shower. I put it in the drain after my shower and let it do its work!

The enzyme does help with old, cleaned drain odors....there will always be odors depending on the humidity in the air!

I had little faith that this would clear my drain. I have had an extremely slow drain for over two years and was about to have it snaked again about the sixth time. And possibly scoped to see if I needed to dig up my basement floor to fix it once and for all. I put 3/4 cup down the drain once or twice a day and chased it with a quart of water to get it past the p trap daily for about 10 days. I now can run the water all day without it even starting to back up. Yes it smells good but I will maintain my drain with this stuff a couple times a month. What a relief and I didn't even snake it this time. WOW! Thanks for this product.
