Bio Sculpture buffing questions


So I'm booked to do my training in April (so excited!!) but I'm trying to get everything together for the salon before then - I was just wondering whether everyone uses a 240 grit buffer to remove shine and then either a 100 or 180 grit to break the seal for removal?

On a separate note - do you all rinse your tools after disinfecting in barbicide/mundo or do you just dry them thoroughly? Have seen conflicting info on this!
