Cleaning dried wax off of decals?

Thanks everyone for your suggestions. When we get to warmer climes, I will follow these up.

Back when I was a dumb kid decades ago, I had gotten as far as getting paste wax put on my car, then got distracted and it all dried. It was white and hard as a rock not to mention impossible to get off. So I asked an older gentleman how to remove the dried wax. The answer was to apply a fresh coat of wax over the dried wax and wipe it off before it dries. Son of a Gun....it worked.

Now down side to the wax on the decals is that it may have dried out the decals over time. If this is the case it is a whole different matter to deal with.

Good Luck

You can't just wipe it off with a soft dry rag?

Diluted Awesome on a barely damp rag will do it. Rinse well when complete.
