The best way to stay clean when dumping an RV tank is to wear protective gear, such as rubber gloves, glasses, and waterproof clothing. Invest in a quality sewer hose and use a secure connection to avoid any spills. It is also important to use plenty of biodegradable detergents and cleaners to break down waste before dumping the tank. Finally, use a clean-out port to prevent any unpleasant odors.

When cleaning your waste tank, keep in mind that the chemicals you use should eliminate odors, keep sensors clean and working, prevent clogs and waste accumulation, and be suitable for all camping styles. It is highly recommended that you use a biodegradable waste tank chemical designed for your specific waste tank. Generally, you should use specialized RV holding tank chemicals, such as RV Digest-It, Bio-Clean, RidX, Formaldehyde, Phenol, and Chlorine. These products contain beneficial bacteria that help break down waste and reduce unpleasant odors.

You can clean the freshwater system in your travel trailer by following these steps:

1. Turn off the water heater and drain the water

You should not keep your water heater on when you want to clean your water tank, so it does not get damaged. Drain all the water in the freshwater system after turning the heater off.

2. Divert your RV water heater

You will achieve this by closing the valves that control water in and out of the heater. If you have an ice maker or an onboard water filter, you should close them as well.

3. Add diluted bleach to the water tank

Pour fresh water to fill about one-third or half of its capacity. Then add diluted bleach based on the quantity of water. Add one ounce of bleach per eight gallons of water in your tank.

4. Fill the fresh water tank with clean water

After putting in the fresh water and the bleach mixture, fill the tank. It should be full to the brim so the sanitizing solution can reach the nooks and crannies of the system.

5. Open every faucet and run them until you smell the bleach

When the tank is full, open all the faucets one by one until you perceive the bleach. The bleach smell is an indicator that the solution has passed through all the pipes.

6. Leave the sanitizing mixture for some hours

Leave the sanitizing mixture in the tank for about eight to twelve hours to ensure it gets thoroughly cleaned. You can take your RV for a short ride to splash the sanitizer around the system as much as possible.

7. Drain the freshwater system and flush it with freshwater

After letting the sanitizing mixture sit for a while, drain the tank completely from the low-point drain. When the tank is empty, refill it with fresh water and run each faucet until you can't smell bleach. If you are certain that all the bleach is out, refill the tank and return the ice mater, water heater, water filter, and other appliances as they were.
