Key item features

  • Odor Elimination: Mineral-based formula effectively eliminates foul odors in RV, camper, and marine holding tanks, ensuring a fresh and clean bathroom environment after each use.
  • Waste Flow: Promotes smooth waste flow and prevents buildup, clogs, and recurring odors in black tanks, unlike enzyme treatments that over-liquefy waste.
  • Long-Lasting Control: Concentrated treatment provides reliable, long-term odor control between dumps, with each scoop treating up to 40 gallons for both black and gray tanks.
  • Tank Compatibility: Safe for use in all RV and marine holding tanks, including black tanks, gray tanks, and septic systems, across various vehicle types.
  • Easy Application: Simple application involves adding the measured amount with water to the RV black tank after dumping, or flushing down the RV toilet or sink for gray tanks.
  • Maintenance Solution: Ideal for routine RV holding tank maintenance, winterization, or long-term RV storage, keeping tanks clean and healthy.

Happy Camper RV black tank deodorizer

We tried several black tank deodorizers before we tried Happy Campers. This product was easy to order and shipped fast. It definitely does the job. We have had no issues with bad smells since we started using it. It is easy to use and is very effective. We will continue to use this great product.

Does the Job

This type of stuff is pricey. It does the job. Not sure if there is a less expense alterternative. I will look into that next time. I recommend this product just check on cheaper options but make sure your comparing apples to apples as far as ingredients and ozs.
