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

This worked super well - smells went away in less than a week -I use a little weekly now and drains are fresh

2.5 years ago I bought a 1940’s house in the Midwest (with a basement). The basement stunk. The smell would waif up into the main floor and stairs to the second floor. 3 months after buying my house I found out the basement had foundation problems and had to invest $30k to brace the walls. I thought that would solve the smell. 2.5 years later the smell is still there as strong as ever. I hated my house. No one wants their house to smell like a sewer. I tried everything. Moping the floors, bleaching EVERYTHING, coal packets, even air fresheners.Years of research I came across an article that stated the smell could be coming from the drain.ONE APPLICATION. That’s it. One application and my basement does NOT smell. I cannot recommend this product enough. The only complaint I have is that I didn’t find this sooner.

Ended up, over the course of about a week, to use the entire bottle on our shower drain. It defiantly improved it quite a bit, but not sure the Oder is completely gone yet.

Very stinky drains in 20 year old house. Tried bleach, concentrated vinegar, etc. They worked for hours to days. After 5 days of using this product, the house smells like a petunia. That's a figure of speech. Bioda has a very mild scent, not a strong chemical odor at all. It just works. A pleasant surprise in a sea of typically overstated product capabilities. Will update if the stench returns.

Eliminated Oder but comes back, prob not worth the purchase
