Filter cartridge containing vinegar wetting cotton for descaling flow passages

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

• placing a container that is closed by a lid in a beverage filter cartridge machine, the container having on open top closed by the lid and storing a liquid absorbing material and vinegar within confines of the container, the lid having an inlet opening and the container having an outlet opening;
• and
• flowing heated liquid through the inlet opening and into the confines of the container from said beverage filter cartridge machine to mix with the vinegar to form a liquid mixture wetting the liquid absorbing material, the liquid mixture releasing from the liquid absorbing material as the heated liquid continues to flow through the inlet opening to enter the confines of the container after the liquid absorbing material has been wetted by the liquid mixture, to pass through the outlet opening in the container and thereafter descale flow passages of the beverage filter cartridge machine.

An apparatus suited to descale flow passages of a beverage filter cartridge machine, comprising:

• a container having on open top closed by a lid and that stores both a liquid absorbing material and vinegar within confines of the container, the lid and the container having an inlet opening in the lid and an outlet opening in a bottom of the container so that as heated liquid from the beverage filter cartridge machine flows into the confines of the container via the inlet opening, the heated liquid mixes with the vinegar to form a liquid mixture wetting the liquid absorbing material, whereby as the heated liquid continues to flow into the container via the inlet outlet after the liquid absorbing material is wetted, the liquid mixture releases from the liquid absorbing material to exit the container via the outlet opening and thereafter descales flow passages of the beverage filter cartridge machine.
