I usually bathe Jaya and Jenna every two days, so that is when I remove the gunk from their eyes. After their bath, I just use a comb and comb it out.
Both mine had issues with it (and everything else), but you must perservere... be persistent - after a few times (or more

), they will just sit there quietly and accept it.... you may have to endure a few dirty looks haha...
What I used to do with Jenna is roll her up in her towl so that only her head would be peeking out. Then I'd hold her between my legs while i sat at the edge of the tub, or just have her lay tummy side up between my legs, and then hold her head (gently) with one hand and comb out the gunk with the other.
What I found really got them used to it was to use my fingers initially. Neither of them would do anything if i had my fingers in their face, but they'd freak out if the comb was there. So, once they stopped fussing over my fingers, i slowly introduced the comb.
I know its gross using your fingers, and its not nearly as effective, but for me, it was the only way..... plus..they're like my babies so I didnt mind too much.... (if we can pick up poop, and change our skin babies poopy diapers, a little eye-gunk is nothing

)
hope that helps!
