Apparatus for descaling a single serve beverage filter cartridge machine with apple vinegar wetting cotton in a beverage filter cartridge

A method suited to descale flow passages of a beverage filter cartridge machine, comprising:

• providing an outer container that is impermeable yieldably-piercable and cup-shaped and internally subdivided by a permeable cone-shaped filter into first and second chambers, the first chamber being configured to store a granular or powered dry beverage medium, the container being closed by an impermeable yieldably piercable lid;
• storing a liquid absorbing material and apple vinegar in the first chamber;
• piercing the cover to admit heated water during a brewing cycle for infusion with the vinegar to produce a heated mixture of water and vinegar;
• exiting the mixture through passageways of the permeable cone-shaped filter that promote full saturation of the mixture in areas adjacent a sidewall of the outer container to descale or cleanse of accumulated excess grinds and muck;
• and
• piercing a bottom of the outer container to accommodate outflow of the mixture from the permeable cone-shaped filter.
