This topic is about testing and comparing different ostomy deodorizer drops to find an effective and affordable solution for controlling odor. The focus is on Pure Bio-Clean Solutions drops, which are being evaluated against other options like M9 drops. Here's a summary of the experiences and advice shared:

- The first bottle of Pure Bio-Clean Solutions drops was not effective. After feedback, the company reformulated the product twice. The latest version is better, but still not perfect, especially for morning use after overnight.

- The originator is considering trying Na’Scent drops and asks for opinions on M9 drops. They find M9 effective for odor control but dislike the blue dye.
