Food buildup in deformed beak

[sproch1976]

This little polish has a deformed beak. It eats and drinks ok but there is all kinds of food built up in the lower beak. I try my best to clean it with warm water and a qtip but I can't get in the middle. Does anyone have any ideas on a better way. I have thought about trying a syringe but I'm afraid of getting water into its lungs. I really won't open its mouth. I've trimmed and filed beak as low as I can without hitting the quick

Eats and drinks. 3/4 the size of the other polish we got the same day. I clean it's beak but still has did build up I can't quite get out under it's tongue.

Could you take some of the build up out of its mouth and take a picture?
Are you sure it's food?
