Camco Rhino Holding Tank Cleaner Drop-INs - 6-Pack

The Camco Rhino Holding Tank Cleaner Drop-INs 6-Pack treats black water holding tanks with a powerful enzyme complex designed to dissolve waste and prevent odors in RV and marine systems. Each pre-measured Drop-IN treats up to a 40-gallon tank, making this the go-to solution for boat owners and RV enthusiasts who need reliable holding tank maintenance without the mess of liquid treatments or powder formulations.

These enzyme-based drop-in cleaners work by breaking down solid waste and organic buildup that accumulates in holding tanks over time. Regular use keeps tank sensors functioning accurately—critical for onboard monitoring systems—and eliminates the sulfur-based odors that plague poorly maintained tanks. The formula is safe for all septic systems and contains no pesticides, making it environmentally responsible for both freshwater and saltwater boating environments. The convenient six-pack format means you have a full season's supply without frequent reordering.

Holding tank maintenance is often overlooked until problems emerge—sensor failures, blockages, or persistent odors that signal neglect. Boat owners facing extended trips, liveaboard situations, or high-frequency use benefit most from proactive treatment. Weekend fishermen running weekend cruisers and serious offshore anglers maintaining larger vessels alike rely on consistent tank hygiene to avoid costly service calls and cabin comfort issues. Dropping one treatment into your tank every 40 gallons of capacity takes seconds and provides weeks of chemical support for natural decomposition.
