Professional Strength Enzyme Drain Cleaner, Septic Safe Drain Odor Eliminator, Smell Eliminator

This product worked as described and left my drains smelling great.

Works great for deodorizing an untraceable odor from a little used toilet. We pour in to the toilet bowl, and the sink, and it helps deodorize the odor, and needs to be repeated after a few days/flushes.

I moved into a new house and the shower drain was pretty rancid. I tried cleaning it with bleach and to no avail could I get the smell away. After using this product only a few times the smell is gone and I haven't had to reapply it either. It definitely eats the enzymes that create the bacteria of the smell. I highly recommend it

This stuff works pretty good on reducing shower drain smells, but I had to use it several days in a row to get the smell to completely dissipate

This stuff really does work! I had a bad smell coming from my shop sink drain and this has helped take it & keep it away. I highly recommend this if you have smelly drains!!

I used Bioda Professional Strength Enzyme Drain Cleaner mainly to deal with drain odor, and it does a decent job eliminating unpleasant smells. After treatment, the sink smelled noticeably fresher, and it seems safe enough for regular maintenance and septic systems. However, I didn’t notice any real improvement in water drainage. If you’re expecting it to clear slow drains or remove buildup significantly, the results may be limited. It works better as an odor eliminator than a drain unclogger. Because it handles smells but doesn’t noticeably improve water flow, I’d rate it 3 stars. It’s useful for maintenance, but not a strong solution for drainage issues.

This product gets the job done. I was looking for something septic-safe and a healthier option to use around the house, and this has worked well for me. It does take about 2–3 days to fully start working, so a little patience is required, but it’s effective once it kicks in. I follow the directions on the bottle (sometimes using a bit extra) and apply it once a day in the evening after I’m done using the shower or sink. I continue until the clog clears. Most of my issues are hair-related, and this product handles them well.

This stuff is AMAZING!!!! I don't use one of my bathroom sinks and I rarely use the garden tub so when water doesn't regularly run down those pipes it starts to smell! I honestly thought there was something wrong with sink faucets water supply because I only smelled a horrible smell when I turned the water on. After I poured this cleaner down all of the drains in the bathroom and let it sit over night I woke up to my bathroom smelling like mint!!! My sink in my kitchen also had a horrible smell so i poured this stuff down the garbage disposal side and the other side of the sink and this morning there is no smell in my kitchen!!!
