After use, simply unscrew the lid and pouch. The bottle and lid can be cleaned either by hand or through a dishwasher (the pouch is best cleaned by hand). The opening has been designed as wide as possible to allow most tap heads to fit inside. Being a soft-flexible material the pouch is best cleaned using warm water and rubbing any excess gel out.
For a deep clean the lid and mechanisms have been designed to fully dissemble. This is carried out by depressing the two prongs underneath the lid and pushing the components upwards.
