Review: Resolved bad taste and odor first time - Purchased camper 3 months ago and water had awful taste and a chemical odor. Did a bleach treatment and NO change. Terrible chemical smell and awful taste. Purchased this kit and used as directed and I am very happy to report the smell is gone and the taste is perfect!

### ⭐⭐⭐⭐ Good product, but a little taste and foam or a bit.
*by B***9 on February 27, 2025*

Used to disinfect our brand new camper water tank. Was easy to use when following instructions. After all said and done it had a little bit of taste for a few tanks of water and did foam up for while but taste and foam went away after a few tanks. We even dumped a full tank after the treatment. Overall good product. I feel that it did a good job cleaning and I would buy it again.
