Save money the smart way: Buy a replacement pack and reuse the 360° Profi spray pump. If the complete pack is empty, unscrew the ergonomic 360° Profi spray pump and rinse the mechanism under running water by holding the chrome steel pull-on filter in a container of warm water and pumping it a few times. If the product has not been used for too long, the nozzle may become clogged. After rinsing, the pump is fully functional and can be screwed onto the replacement pack.
