Knocks Out Odor Kit

Knocks Out Odor Kit – Natural Holding Tank Treatment & Toilet Cleaner System

Say goodbye to harsh chemicals and lingering odors with the Knocks Out Odor Kit, a two-part system that combines the biological power of K.O. Kills Odors and the fresh-clean performance of C.P. Cleans Potties. Together, they create a naturally effective, marine-safe solution for keeping your toilet system odor-free, clean, and functioning at its best.

Step one: add K.O. to the holding tank. This powerful bioactive formula introduces beneficial bacteria that begin breaking down waste immediately—safely, efficiently, and without synthetic chemicals. It relies on proper system venting and zero chemical interference to thrive, converting waste into odorless liquid while preventing buildup that causes clogs and foul smells. Just one treatment can keep your system clean and odor-free for extended periods.

Step two: use C.P., a unique non-toxic toilet bowl cleaner formulated to maintain the delicate bio-balance established by K.O. It contains a specialized strain of bacteria combined with 100% biodegradable cleaning agents to keep your marine toilet bowl fresh, gleaming, and odor-free. Each flush continues the cleaning process and enhances the performance of the holding tank treatment.

Unlike chemical-based products, the Knocks Out Odor Kit doesn’t just mask smells—it eliminates them at the source using nature’s own methods. It’s important to avoid any other cleaners or chemicals while using this system, as they can kill the beneficial bacteria and diminish the effectiveness of the treatment.

Ideal for eco-conscious boaters, the Knocks Out Odor Kit delivers an all-in-one, non-toxic waste management and toilet cleaning solution that works with your system—not against it. Safe, simple, and highly effective, it’s the clean marine solution your head has been waiting for.

Knock Out Odors Kit KO2

Eliminate rotten egg smell In all raw water toilets with this simple system.

By drawing a small amount of C.P Cleans Potties into the incoming water the rim of the bowl will be fully treated with a non chemical enzyme that prevents that horrible rotten egg smell. Most owners do not realize that it is the seawater and brackish water organisms dying in the rim of the bowl that sit until next use. No amount of cleaning or chemical used in the bowl can prevent the odor.

The key is to treat the water before it enters the rim of the bowl.

This kit is specifically for use with raw water toilets as freshwater toilets do not suffer from the same issues because freshwater should not contain organisms. Proper use of this kit will help to keep your entire sanitation system smelling fresh not offensive! Nobody steps on a boat and wants to smell the unpleasant odors that can be associated with a sanitation system in poor working order. The first step starts with the C.P. being added to each flush to prevent the outside water from being overwhelming when the first flush is initiated after sitting for a period of time.

In addition to treating the incoming water we include the K.O. Kills Odors to add to the holding tank. 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 breakdown 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 it 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!
