TIPS FOR TANKS Using Happy Campers
Story courtesy of Happy Campers GREY TANKS 1 You do not need to treat this tank every time you dump, but if your grey tank gets an odour the bad stuff usually grows from the top of the tank down. If this happens, you need to treat it with HAPPY CAMPERS (two or three scoops should do it). Easiest way to treat the odour is to sprinkle and stir 2 or 3 scoops into a large bucket until well dissolved and pour down the kitchen sink. Then finish filling the tank and let sit over night. If you are moving right away you can do the same, even better by filling the tank to approximately 2/3 full for agitation while traveling and rinsing it when arriving at your next destination.
2 We recommend you treat the grey tank every third time you dump. For normal treatment, fill the sink with approximately 4 l (1 gal) of water. Sprinkle & stir ONE scoop of Happy Campers and immediately drain sink.
3 GREASE: If you have a build up of grease in the tank, put 60 -90 ml (2 -3oz) of Original Blue Dawn (dish soap) in the tank to solve this problem.
4 NOTE: Never use antibacterial soap or disinfectant cleaners in your tanks because they will stop the action needed
