Knocks Out Odor Kit
Kills Odors works exceptionally well with good venting. No chemical can be used in the toilet as it will kill the good stuff in KO designed to naturally break down the holding tank waste while minimizing the odor. The second step is to add the K.O. to the holding tank to naturally break down the waste. With each flush, the C.P. will not only prevent odors but will also help to keep the bowl sparkling clean and smelling great! If a little extra cleaning is necessary, just squirt some C.P. in the bowl to clean it!
No other cleaning product should be used with the K.O. Other cleaning products will reduce or completely eliminate the effectiveness of the K.O.

- Treats incoming water with each flush
