Re-using RV Anti-Freeze

I winterized my RV last year with RV antifreeze. I did not use the camper this summer or fall and never anti-winterized it. Will the antifreeze last a second winter? John V., (Mt. Vernon, IL)

John, the short answer is yes; performed properly, a winterized RV with RV anti-freeze will still be viable for a second winter. In fact, in my training seminars, I recommend capturing the anti-freeze during the de-winterizing procedures after the first winter and re-using it again for a second season. You can always "test" the liquid to be sure, but I've heard from many RVers who re-use the RV anti-freeze. After the second winter, it’s probably best to replace the anti-freeze for the next winterizing procedures however. It depends on the severity of your winter season, but it’s entirely possible to use the same RV anti-freeze for at least two seasons.
