Ah, the joys of RVing! Endless adventures on the open road, beautiful campsites, and the blissful feeling of freedom. But amidst all the excitement, let’s not forget a vital task – cleaning your RV water tank. This often-overlooked chore is essential for maintaining a clean and healthy water supply, and we’re here to guide you through the process. So grab your rubber gloves, put on your cleaning hat, and let’s get started!

Preparing for the Cleanse

Before diving headfirst into cleaning your RV water tank, make sure you’re well-prepared. Start by gathering the necessary supplies – a pair of gloves, a long-handled brush, a non-toxic RV tank cleaning solution, fresh water, and a hose. And of course, a dash of motivation to make the cleaning process a little less daunting!

Draining the Tank

Now, let’s get our hands dirty – quite literally! The first step in the cleaning process is to drain the tank. Find the water tank drain valve, usually located under the RV, and attach a hose to it. Open the valve and let the water flow out, bidding adieu to any unwanted dirt, debris, or mysterious particles that may have snuck in. Once the tank is empty, close the drain valve, and it’s time to move on to the next step.


With an empty tank, it’s time to scrub away any residual grime. Mix the RV tank cleaning solution with fresh water according to the instructions on the bottle. Pour this mixture into the tank and let it do its magic for the recommended amount of time. Then, grab your long-handled brush, put some elbow grease into it, and scrub away at the inside of the tank. Make sure to pay extra attention to the corners and hard-to-reach areas – those stubborn spots love to hide!

Rinse and Repeat

After diligently scrubbing away, it’s time to rinse out the tank thoroughly. Attach a hose to the fresh water supply and run it into your RV’s tank until it’s full. Open the tank drain valve once again, letting the water flow out along with any remaining cleaning solution. Keep repeating this process until the water runs clear, indicating that the tank is squeaky clean and ready to be refilled with fresh water.

Prevention is Key

To ensure you don’t find yourself knee-deep in the cleaning process too often, it’s essential to take preventive measures. Regularly sanitize your RV water system by using non-toxic RV-safe sanitizers. Additionally, always use a fine-mesh filter when filling your water tank to prevent debris from entering in the first place. Lastly, keep an eye out for any signs of contamination, such as foul odors or unusual tastes, so you can address the issue promptly.

Cleaning your RV water tank may not be the most glamorous part of RVing, but it’s an essential task to ensure a healthy water supply during your adventures. By following these steps and staying vigilant about prevention, you’ll be able to enjoy clean, refreshing water – the perfect companion on your cross-country journeys. So, raise a glass (of clean water), and here’s to many more clean and memorable RVing experiences!
