LBlack14 how the heck would I get in the cavity, cuetips?
What @darpar and @Eguller described should work in the cavity, Landon. You'll have to fold a smaller wipe to fit. If you use a paint fill marker with a small or medium tip and try to fill JUST the letters, there won't be to much over spill to clean. Let it ALMOST dry and wipe (don't press) lightly. What is left can be cleaned with a razor, or dental pick. Those tight spots take practice. The good news is, you can start over many times.
