Dear Paul
We use Klohen Syrings and we rinse them 1-2 times with distilled water
after each loading
If it is clogged we rinse it many times until the water enter the needle
and than we leave some water inside for 1-2 hours.
I think it is very important to rinse the syringes after each loading to
avoid any problem.
