Venting
Have you ever heard the expression, “fighting fire with fire”? Well this is somewhat similar. When you’re fighting grub and grossness, use some kind of grossness to your advantage. Don’t take this too literally, I’m talking about silica gel to manoeuvre itself between the AC grid to pick up dirt.

Did you think that silica gel was only good for the dusty AC vents? It sure is useful for many other roles, like retrieving small objects that are lodged in hard-to-reach places. You can also gently press the gel over buttons on your radio and dashboard.
