How To: De-winterize Your Airstream
With warmer weather on the way, many people are getting the itch to travel. If your Airstream has been in storage for any period of time, you will need to de-winterize before hitting the road. Below are some of the steps to get your Airstream ready for the travel season. If you are unsure of any of the steps below, we offer a de-winterizing service at Colonial Airstream.
Clean & Inspect Exterior
If your Airstream was stored outside during the winter, it will need a good cleaning. When washing the exterior, we recommend using just soap and water. If using cleaning products, be sure they are safe for clear coat finishes.
After washing, apply a wax such as Walbernize RV Super Seal. Spray the wax onto a soft rag and work with the grain of the aluminum to avoid tiny scratches or swirl marks.
Flush Plumbing
If your Airstream was winterized, there will be RV antifreeze in the plumbing lines. Before using your water system, the antifreeze must be flushed out.
Start by closing the low point drains and connecting a freshwater hose to your trailer’s freshwater inlet. Turn on all faucets and showers—both hot and cold—to clear the plumbing lines. If your trailer has a water heater bypass valve, open it to allow water into the heater. Check for leaks during this process.
Some water will enter the gray and black tanks. Once a tank is full, open the exterior drain and let the water run until the tank is empty. Once done, the system is ready to use.
Inspect Batteries
Your Airstream’s battery system is essential—without it, there is no power. First, inspect the battery for cracks or corrosion. Clean it if needed.
If stored for a while, the batteries may need charging. You can charge them using your Airstream’s converter/charger. Turn off storage mode and connect to shore power to begin charging. Solar panels can also be used if available.
If you have lead-acid batteries, check and refill water levels with distilled water if necessary. Always wear gloves and eye protection, and wash your hands afterward.
Inspect Propane
Reconnect your propane tanks and inspect all connections and hoses. Look for wear or damage. Use soapy water or a gas detector to check for leaks.
Propane tanks must be recertified 12 years after their manufacturing date. Look for the certification sticker to verify your tank’s status.
Inspect Tires
Before hitting the road, inspect your tires for cracks, wear, or damage. Inflate them to the recommended PSI. Don’t forget to inspect your spare tire.
Now is also a good time to check and tighten lug nuts if needed.
