Odd Question

I just noticed that someone hit my TT with three eggs sometime over the last few days! It's been cloudy/rainy lately, but full sun is coming back this afternoon, and I'm at 5,000 feet elevation so it will be intense. I've heard that egg can be difficult to clean off of many surfaces. and I think I need to get right on this before the sun bakes it.

This is on a fiberglass-sided Jayco that is almost 11 years old. The gelcoat has faded/oxidized but the surface is still very smooth to the touch. Does anyone have experience or suggestions re getting egg off an RV?

Thanks!
