As I said ! acetone will not remove dried CA at once...neither will nitro .
That's not what you said...

you said acetone will not work.

But! Nitro will remove dried Ca glue much faster than acetone.
Acetone takes an awful long time to desolve Ca glue compared to nitro.
I disagree. I've tried both.
"Soaking" CA in Acetone does the best job and works rather quickly.
Usually the CA becomes putty like in 5-10 minutes of soaking, and then can be easily removed using the Acetone-toothpaste method.
They key is to keep the Acetone from evaporating.
Try it sometime. There is a vast difference using acetone this way, than say simply applying it with a cloth and wiping...
