If there are ridges, polish the needle by pulling it through a folded piece of
fine emery paper between your finger and thumb until the ridges are gone.
Be careful not to modify the special blunt tip of the syringe.
3. Check for a sticky plunger. Slide the plunger of the syringe up and down a
few times. It should move smoothly without sticking or binding. If it is
sticky, remove the plunger, and clean it with solvent.
