This really works on keeping the head smell neutral. We have been using it for about 2 years without any problems!

Great price for a large quantity, and it does what it’s supposed to do… keep from having a smelly potty experience!

This is a good value. We used it in a marine head and it does seem to help.

We have been having odor problems for months now, and have tried many many products! This took care of the odor problem in our 36ft RV. So happy, and thank you for a great product! We use it consistently in both our black and grey water tanks, and have not had an odor problem since!

My husband and I are living in our RV as we remodel our house. The product we were using simply could not keep the RV fresh smelling under our new living conditions. This product took care of any lingering odors! We poured some into our sinks, shower and toilet. What a difference. Thank you!
