Our first winter out, our tongue jack froze! Anyone have an easy solution to prevent this from happening again? Before we left the drive, we had used an entire can of silicone spray. There has to be a better way.
Need I mention we are new to camping??
Thanks for any suggestions.
You have gotten water/moisture in your jack. A plastic bag, bucket,... anything to keep the weather out helps.
Silicone sprays are great lubricants but don't do much for the ice in the jack. The 'WD' in WD-40 stands for water displacing. Add some heat to the jack using a hairdryer or heat gun, and a liberal dose of DW-40. In a pinch a deicing product for auto windshields or locks will work. Anything that melts the ice/frost and you should be good to go.
