UPDATE!!
To ease the process remove caps while fresh sooner the better. Take a razor and cut around base of spur cap. Use a pc of vinyl hose to slip over cap and use a pliers to twist and pull off cap. Doing this makes bone cleaning much easier and faster, and you can eliminate the BLO on the caps later if you wish. I still do it though.
Rest of the process is the same. Just be careful with the pliers and the caps as you could crack the cap and or leave the tooth mark of the pliers in the cap. But its another option.
