Something stuck in vents?

So my little Dinky likes to dig in his substrate and he has a little bit of coco husk in his vents, is there any particular way I should clean them out?
I've rubbed my finger over them and they've fallen out easily, I just want to know in case he really gets something stuck in there.

You are referring to the heat pits on the face?

If you are referring to the heat pits then it should be fine. Keep in mind BPs are head shy so it may be best to not stress him out. It really doesn't make any sense to dust him off if he is just going to get dirty the moment you put him back in his enclosure. I also wouldn't be sticking anything in his heat pits to dig out dirt. If it falls out itself, I wouldn't worry about it.
