I grabbed the thin CA instead of the med CA this weekend.
Splash, all over my hand.
I still have some under my wedding ring.

I have used all of the above methods.
I like sandpaper when CA and balsa is attached.
Most of the times I just wait and pick at it, it will come off.

P.S.

CA is nothing, I fried my hand twice with the soldering iron this weekend. I will take the CA anytime.
