Used this for an entire year in my rig with a family of four. Seems to do a fine job. No noticable oders from traps or outside vents. My tank sensors worked well all year. No plumbing issues whatsoever. I guess it did its job as the package described.

Does this solution expire ? Just bought an RV and there's an open bottle in the cabinet, but we don't know how old it is and if it is still effective.
