Regular maintenance and emptying of the septic system can be daunting. Keeping your RV holding tanks clean is work. If you have not used your RV holding tanks before or you just want to learn more how to keep them sanitized, you will need to find the right treatment. I personally prefer greener products, I don’t like to use toxic chemicals in my living space. I’ve been researching for natural holding tank cleaners.
Firstly, you should understand that there are three types of RV Holding tanks you have; freshwater tanks, grey water tanks, and black water tanks. We won’t be talking about your fresh water tank now only the gray and the black water tanks. The RV holding water tanks should be emptied before they are two-thirds full for easy flow. To empty the tanks, you will need a sewer hose, treatment, and gloves. Make sure that you dump the wastewater into the dump stations. To maintain your RV holding tanks, you should clean and sanitize them to prevent future problems. Here are five the best natural holding tank treatments that I’ve found:

1. Caravan Full-Timer RV Holding Tank Treatment
