I would say just let her crawl through a wet towel every couple of days and it should eventually come off. There is a way to try and remove stuck eyecaps with Q-Tips, but you would need to use the "Search" function to find the threads with the exact procedures, and I think it's mostly used when there are multiple layers of stuck eyecaps. Usually the wet towel will work or it will come off with the next shed, as long as the humidity is good...
