Bioda Professional Strength Enzyme Drain Cleaner, Septic Safe Drain Odor Eliminator, Smell Eliminator, 1 Gallon

Bioda really works! We tried everything mechanical to get rid of the awful smell in our bathtub drain and nothing worked until we used Bioda. We removed had all clogs, used baking soda and vinegar and anything and everything else. While my husband kept trying these methods, I ordered Bioda Enzyme Drain Cleaner based on an Amazon customer review and within a few days of regular use, the odor is gone!! Thank goodness and thank you, Bioda!!

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.

What an amazing product!! I normally don’t leave reviews but I am blown away. I had a shower drain that had a terrible smell coming from it from the first day we moved in. I put this drain cleaner in overnight and the smell is completely gone now over a month later! Fantastic product, worth every penny!

this works for odor control but you must use it weekly to build the enzymes up in the pipes over time. after that you can back usage down to every other week or less. we had drain odor in the shower and it was gone overnight. the negative is that it’s difficult to pour down sink drains because the container is so big and the faucet gets in the way. i would prefer this as an enzyme tablet to drop down sink drains.

This stuff definitely works. I'm impressed

Eliminated the bad odor in my pipes on first application!

It worked really well, drains clears faster.

Wow - moved to a new home and it was NOT disclosed that it was septic. Because I live in this small town, they put in a "hybrid" septic and is completely managed by the city. City manages the pumping and all that. Just got pumped and OMG - the smell from the shower drain was awful. Got this - did it kind of extra - but in three days the smell is gone. Glad I have this. Plus - I have pets and will be using this to clean since it is far better than any other "pet" enzyme cleaner. This stuff has a very faint fresh smell. Really like it.
