How to Get RV Antifreeze Smell Out of Tank
- 1). Connect your RV's freshwater hose from a freshwater source to your RV's freshwater port. Hook up your sewer line from your RV's waste port to a drain or sewer hookup. If you don't have convenient hookups at your home, connect your RV at a nearby facility. Water and sewer hookups are frequently available for no charge at RV sales and service companies, or an area campground may charge you a small fee to use their facilities.
- 2). Open your sewer drains and allow any antifreeze in the sewer lines to run out, though your tanks should still be empty. Flush your freshwater lines by opening your cold taps on the sink and tub faucets one by one. Allow fresh water to run through the plumbing for several minutes. Turn on the hot water faucets one at a time to rinse the hot water heater and the hot water lines. Run fresh water through each line until the water no longer has any odor or color. Turn off all faucets.
- 3). Sanitize your RV tanks and lines with a diluted bleach solution. This removes any lingering residue from the antifreeze and prepares the freshwater lines for use. Pour 1/4 cup of bleach in your water tank for every 15 gallons that the tank holds. Fill the water tank. Flush out each line by turning on your faucets, one at a time, and letting it run for several minutes. Keep running water until you can't smell any bleach any longer. You may need to add water to your water tank or hook directly to a freshwater source to allow enough water to rinse the bleach out of the water system.
- 4). Smell a sample of water from your RV faucet. If the entire bleach mixture has been drained from the water tank, yet the odor of bleach or antifreeze remains, then mix one cup of baking soda into one gallon of water. Pour this mixture into your fresh water tank. Fill the tank the remaining way with fresh water. Flush as instructed above and retest for any odor of antifreeze or bleach.
