Before first use and after every use, remove all pump parts from the breast pump and disassemble all components before cleaning. The pump device, power adapter, manual handle with pivot, and silicone tubing should not be washed or sterilised.
Wash all parts with undiluted baby bottle detergent using a soft bottle brush.
For duckbill valves, avoid using any tools. Instead, apply a small amount of detergent and gently rub along the rims to remove any milk residue.
Rinse all parts thoroughly under clean running water.
Proceed with your preferred method of sterilisation.
