Method for charging an aerosol container with fluid, comprising:—providing an aerosol container (1) having a reservoir (2) comprising a product, for example a foodproduct, and having product discharge means (1a);—gradually supplying fluid to the reservoir of the container (1) via the discharge means (1a) thereof; and—applying a mixing movement to the container (1), preferably during the supplying of the fluid, to mix the fluid and product at least partly with each other, wherein the mixing movement is such that at least a first virtual point (P1, P2) of a virtual center line (Z) of the container reservoir (2) follows an endless path around a respective virtual axis. Embodiments of the invention also provide a cleaning method and a dummy container.
