Abstract: An ostomy bag cleaning appliance for cleaning an ostomy bag comprising a housing with a sealable top to prevent soiled water from splashing outside the cleaning appliance when in use, a mounting plate located within the housing for mounting a soiled ostomy bag, and a nozzle that projects through the mounting plate and into the mounted ostomy bag. A conventionally known attachment appliance which corresponds to the dimensions of the user's ostomy bag, can be affixed to the mounting plate so that an ostomy bag can be installed within the cleaning appliance. The head of the nozzle projects through an opening in the mounting plate and into the ostomy bag and provides a multi-directional stream of water into the ostomy bag. The nozzle provides a stronger flow of water downwards into the ostomy bag causing sufficient agitation to break up solid body waste within the ostomy bag.
