Sunnyside, WA | Spring inside gets sticky from different vaccines. We rinse them out at the end of use with warm water only. No soap or any additive or it eats into the rubber. When I first start the day, I fill the syringe and get all of the air out. Then I put my finger where the needle goes (with no needle!) and see if the vaccine pushes back into the bottle or not. Seems if the spring works the first time, it seems to work all day. Cleaning and not leaving vaccine in the syringe seems to be the key. | |
