Emptied a storage locker recently and discovered some old pens I haven't touched in about 15 years.
All Pilot (Left) with a rubber bladder, two Parkers with piston fillers, and three Schaefers with cartridges. Can I clean them up with warm water? They were not put away clean. I think I'll just try run warm water up into the piston and bladder tanks to try wash them out, but wondering how easy it will be to get all the water out. Any tips appreciated.
