Bottle cleaning system and method

A bottle cleaning system comprising a bottle cleaning device, the bottle cleaning device comprising:

• a handle, elongately formed along a longitudinal direction;
• a handle shaft, affixed to and extending from the handle in the longitudinal direction;
• an end cap, comprising a through bore arranged in the longitudinal direction, the end cap arranged in spaced-apart configuration with the handle and movable longitudinally towards and away from the handle;
• a sleeve, elongately formed between and extending longitudinally from the handle and the end cap, the sleeve defining a channel formed longitudinally through the sleeve, wherein the sleeve is compressible and expandable along the longitudinal direction;
• a longitudinally compressible and expandable, first set of bristles, carried by the sleeve, the first set of bristles wider than the handle;
• and
• a second set of bristles, carried by the handle shaft and narrower than the first set of bristles, wherein the second set of bristles is longitudinally movable within and along the channel of the sleeve and the through bore of the end cap;
• wherein
• the sleeve and first set of bristles are compressible towards the handle, and the second set of bristles is exposable out of the through bore of the end cap, by a longitudinal movement of the end cap towards the handle;
• wherein
• the sleeve and first set of bristles are expandable away from the handle, and the second set of bristles is retractable into the through bore of the end cap, by a longitudinal movement of the end cap away from the handle;
• and further wherein
• the bottle cleaning device is spring-biased to move the end cap longitudinally away from the handle, to expand the sleeve and first set of bristles away from the handle, and to retract the second set of bristles and handle shaft into the through bore of the end cap.
