Yeah, it's slow but it works....

Take a rag and soak it in Acetone.

Keep holding it on the area that received the excess CA. The CA will soften.

At this point swipe a part of the rag on the area.

Move to another cleaner but Acetone soaked part of the rag and continue.

As you progress you'll notice that the CA will remove more quickly with each pass.

Keep at it. It may take you 10-15 minutes of doing this to remove everything, but you'll find that you can.

The rag does two things...

1 - It wicks and rubs off the softened CA
2 - It prevents the Acetone from evaporating as quickly.

You'll need to keep the rag or cloth wet with Acetone, and you'll find that it disappears very quickly...
