Do I need to clean the Piston/Cylinder assembly?

Care for your piston and cylinder after every few pumping sessions with the Lactina breastpump or manual breastpump.
• Wash the cylinder, rubber seal, and vacuum regulator ring with warm soapy water.
• Rotate the piston in the cylinder.
• If your piston/cylinder comes in contact with breastmilk remove and wash with breastpump kit.
• Do not use Quick Clean™ Micro-steam™ bag to sanitize the piston and cylinder.
