Dry rock

[RELLIK-REEF]

Hello everyone, so a friend dropped of a couple pieces of rock for me today. I'd really like to use the in the new build. I have plenty of established rock in the other 2 tanks so I'm not worried about them not having bacteria yet.
I have a couple pictures of them. What I don't like is the dry looking worms on it. How can I get these of or do I just need to go the small hammer and chisel route?
Advice appreciated.

Old tube worms
You can break them off with pliers

Chisel, flat blade screw driver, pliers.. choose your weapon.
