Caravan RV Holding Tank Treatment, the full-timer's better solution to completely eliminate odor and liquefy waste. A premium industrial strength bacteria enzyme formula, no formaldehyde or toxic chemicals.
Why no chemicals: Chemical treatments kill bacteria (good and bad), at best they temporarily reduce or cover odor, forming a smelly sewer sludge coating in tank and on sensors. Weak consumer enzyme formulas do half the job, consequently resulting in dirty, smelly tank and stuck level gauges.
Our Solution: Once you upgrade to Caravan, micro-organisms will begin multiplying, as bacteria reproduces it actually creates enzymes. Enzymes break down more complex molecules into something bacteria can eat, completely eliminating sewer odor, sludge, blockages, human waste and all brands of household toilet paper. Resist the old habit of rinsing your tanks, our microbes feed and multiply, becoming stronger and more effective on residual matter.

DIRECTIONS: Avoid rinsing, precharge tank with ample water.
Standard Dosage: 2oz treats up-to 50 gallons
First Time: 4oz
Gray Tank: 2oz
Hot Weather (over 110°): increase as needed
Cassette & Potty: 2oz ea. both upper and lower tanks
Recirculating Toilet: 4oz, remove & clean filter
Do not use bleach or chemicals, keep valves closed while parked, avoid rinsing
Cleaning Tank and Sensors: Level sensors are historically problematic old school technology. Caravan Tank TREATMENT will prevent sludge buildup and most tank and sensor problems. Long term use will eventually dissolve and clear years of crud. For older rigs, especially difficult sensors, plugged tanks, or a fast fix purchase Caravan "overnight" Sensor and Tank CLEANER.
