happened to my pastel last week, I did the soak method a few times, once a day for an hr, for three days, after that I use a warm wash cloth and softly rubed it over his eye it took about 15 minutes first go one direction over and over but gently, then try the other direction, then from tob to bottom then bottom to top, very softly, I had his eye cap on for about a week total, I dont think theres a rush to get it off, but It must be uncomfortable for them.
BTW my pastel is an :cens0r::cens0r::cens0r::cens0r::cens0r::cens0r::cens0r: and it took some time for him to let me get near his head with that washcloth, just be patient, and if he balls up sorta cup him in your hands and wiggle your finger upward from the bottom so he will expose his head, then softly start with the rag. Afterward he was happy and seemed less skiddish in general.
