RV Dewinterization in a few easy steps to ensure a safe, enjoyable season of adventure.<\/h3>\n\n\n\n

There\u2019s a moment near the end of winter when Airstreamers in the northern latitudes start feeling the travel itch. The sun is out, the clouds have cleared, the air is still \u2013 cool but warming enough that we can go outside without freezing \u2013 and then suddenly we\u2019re dreaming about hitting the road.<\/p>\n\n\n\n

For many of us, spring means getting the Airstream out of storage and preparing for the summer travel season. But you can\u2019t hit the road without de-winterizing. While this may sound complicated, it\u2019s not as difficult as one might think. It\u2019s a great opportunity to learn more about your Airstream and its various systems, and the effort you put in now pays dividends down the road. We\u2019ve made the process easy with a step-by-step guide to de-winterizing your Airstream.<\/p>\n\n\n\n

1. Scrub-a-Dub-Dub<\/h2>\n\n\n\n

Outside-in<\/h4>\n\n\n\n

De-winterization starts on the outside and moves inward. The first step is to clean the exterior. Treat the exterior of your Airstream like you would your vehicle. Like most cars and trucks, your Airstream travel trailer has a clear coat applied over the aluminum \u2013 an extremely thin layer of clear paint that protects the aluminum from debris and helps it shine. Look for cleaning products that are safe to use on a clear coat, many of which are commonly available at automotive stores or online at Airstream Supply Company (two <\/a>of our favorites are Glare Ultra Wash<\/a> or No-Wet Waterless Car Wash<\/a>).<\/p>\n\n\n\n

Be sure to use a soft rag and work with the grain of the aluminum \u2013 from the back to the front. Washing your Airstream using and up-and-down motion can leave tiny scratches that will catch the sunlight and look unsightly. Finish with a protectant and polish like 303 Aerospace Protectant<\/a>, RejeX<\/a>, or Walbernize<\/a>.<\/p>\n\n\n\n

For wheels and tires, wash with soapy water or use Glare Turbo Action Wheel Cleaner<\/a>. And for any clear coat nicks or scratches, use a clear coat <\/a>touch up pen. Don\u2019t forget to clean your awning.<\/p>\n\n\n\n

Head Inside<\/h4>\n\n\n\n

Your Airstream is your home on wheels, and you can use many of the same products you use in your brick-and-mortar home to clean up the interior of your Airstream. We love the microfiber cloths from eCloth<\/a> that let you clean up without the use of harsh abrasives, but depending on what you’re cleaning, you may want something more powerful.<\/p>\n\n\n\n

Start by vacuuming to remove dust, dirt, and other debris, and sweeping the floor to collect any remaining dirt. Also, look for any pest traps or repellents you may have put in before storage and throw them away.<\/p>\n\n\n\n

Warm soapy water works well for the flooring, and a Swiffer is a great option for periodic cleaning after you\u2019ve done the deep cleaning work. For the ultrafabrics and the walls, you can use cleaning products like Pledge to clean and polish. For suede leathers, baby wipes are a great option in a pinch. Be sure to not over-saturate while cleaning, and simply let the surfaces air dry.<\/p>\n\n\n\n

Household disinfectants work well on the hard surfaces in the galley and lavatory areas for deep cleaning. And don\u2019t forget to wash and dry any linens that might have been stored over the winter.<\/p>\n\n\n\n

Become a Dewinterization Detective<\/h4>\n\n\n\n

De-winterizing is the perfect time to inspect your Airstream for any regular maintenance issues that may have gone unnoticed last season, and for any issues that may have set in during storage. Walk around the outside of your travel trailer, paying special attention to glass and plastic parts that weather faster than metal. Check windows for cracks and damage, and inspect the sealants to make sure everything is sealing up properly. Inspect accessories like exterior lights, and get a partner to help you test brake lights and turn signals to ensure they\u2019re working properly. Finally, open and close all doors and storage compartments. Keep track of any issues you may find \u2013 most issues that crop up are easily remedied by a trip to the hardware store or a quick order online.<\/p>\n\n\n\n

If you\u2019re comfortable climbing a ladder, get up high to check the roof of your Airstream. Look for damage (or bird nests) on your air conditioner and around the skylights and fans.<\/p>\n\n\n\n

Back inside, check the cabinets, doors, and drawers to make sure everything is working properly. Have a screwdriver handy to tighten any screws that may have worked their way loose. Look for any water stains that may indicate a water leak, and keep an eye out for any spots where pests may have found a way inside.<\/p>\n\n\n\n

2. Battery Check<\/h2>\n\n\n\n

Your Airstream\u2019s battery is one of its most important components. Batteries can be dangerous though, so only inspect them if you feel comfortable doing so. It\u2019s always a good idea to wear gloves and protect your eyes when working with batteries.<\/p>\n\n\n\n

Your best bet for ensuring your batteries are ready to go when camping season comes back around is to remove the batteries before winterization and store them in a cool, dry place. Connecting your batteries to a battery tender or charger<\/a> over the off-season not only ensures your batteries are topped off and ready to go, but a smart battery tender can keep your batteries healthy and extend their lifetimes.<\/p>\n\n\n\n

If you left your Airstream unplugged during the winter (which Airstream always recommends, as it can be dangerous to leave it hooked up to power when no one is around to keep an eye on it), the first order of business is to recharge. If you chose to leave your batteries in your Airstream over the off-season, make sure to inspect the batteries for any cracks or damage. Clean the corrosion off your batteries with a wire brush and take care to inspect the cables for cracks or damage.<\/p>\n\n\n\n

You can charge the batteries with your Airstream\u2019s converter\/charger. Turn off the trailer\u2019s storage mode and connect it to shore power or a generator. If you\u2019re parked in the sun, you can also turn on any solar panels you have installed.<\/p>\n\n\n\n

Lead-acid batteries can be filled manually with distilled water if the levels are low. Make sure to take care not to splash and always wash your hands afterward.<\/p>\n\n\n\n

3. Flush the Plumbing<\/h2>\n\n\n\n

Winterization involves draining all the water out of your trailer and sometimes adding RV antifreeze to ensure water doesn\u2019t freeze in cold temperatures and crack pipes in your Airstream\u2019s plumbing. You\u2019ll need to flush any antifreeze out before hitting the road. Close the low-point drains that were left open in storage, and connect a freshwater hose to your trailer\u2019s freshwater inlet. Watch for any leaks under the Airstream, and then go inside and turn on all the faucets and showers (both hot and cold). This will clear the plumbing of antifreeze. You\u2019ll also want to set your water heater\u2019s bypass valve to allow water into the water heater.<\/p>\n\n\n\n

This is also a good time to add fresh water system cleaner to disinfect and help with any lingering odors before filling your fresh water tank. This will also help remove any residual antifreeze. Once your tank is full, open the exterior drain and let the water run until the tank is empty \u2013 but don\u2019t let the water pump run after the tank is empty, or you could damage the pump. After this step, you\u2019re ready to refill the fresh water tank as soon as you\u2019re ready to hit the road.<\/p>\n\n\n\n

During this process, some water will get into your gray and black tanks. Check outside to make sure neither is leaking and that your wastewater connections aren\u2019t leaking either. This is also a good time to check your sewer hoses to make sure they are in good condition too. Check the dump handles, and lubricate them with some penetrating oil to make sure they don\u2019t stick.<\/p>\n\n\n\n

4. Propane Test<\/h2>\n\n\n\n

Reconnect your propane tanks and inspect the tanks. Propane tanks are labeled with a certification sticker and must be certified at an inspection station 12 years after manufacturing, and then every five years after that. Inspect the connections and hoses, and look for any signs of wear and tear. Use a paintbrush and soapy water to check for any leaks in hoses and connections, or use a flammable gas detector to check for leaks. If you suspect a leak or smell of gas, call a professional or your local dealer to get the problem remedied. As always, better safe than sorry.<\/p>\n\n\n\n

5. Checkup on All Tires<\/h2>\n\n\n\n
\"\"<\/a><\/figure><\/div>\n\n\n\n
<\/div>\n\n\n\n

Finally, check your tires to make sure they are still in good condition. Your tires are the most important piece of the Airstream puzzle \u2013 safe, reliable tires mean safety while cruising down the highway. Even if you have a Tire Pressure Monitoring System, it\u2019s a good idea to check the pressure and add air if they\u2019re running low<\/a>. Don\u2019t be afraid of getting dirty! Get down and crawl under the trailer to inspect the back side of your tires. It\u2019s also important to check the pressure on your spare tire. Nothing\u2019s worse than getting a flat tire and finding out that your spare isn\u2019t inflated! Lastly, check your lug nuts and tighten them if needed. The last thing you want while heading out on an adventure is a blown tire.<\/p>\n\n\n\n

“Safety First” isn\u2019t just a clever phrase. It\u2019s the difference that makes a trip memorable for all the right reasons. Follow these steps to make sure your Airstream is ready to go when you are, and you\u2019ll be able to travel with peace of mind and ease. Access and download your own dewinterization checklist so you can check off all the boxes (please reference owners manual for model specific requirements).<\/h3>\n\n\n\n
