Abstract: A container within which is a liquid absorbing material that is wetted by a wetting liquid. The liquid absorbing material has a liquid retention characteristic for retaining the vinegar—such that the liquid retention ability reduces as a surface tension of the wetting liquid reduces due to a temperature rise of the wetting liquid over time. The temperature rise of the wetting liquid comes about when heated water at a higher temperature than the wetted liquid comes into contact with the wetting liquid. Preferably the liquid absorbing material is cotton and the wetting liquid is vinegar, such as apple vinegar. The container has an open top closed by a cover or lid and has a bottom. After piercing the cover of lid, heated water to pass through to enter confines of the container and heat the vinegar and mix with it for cleaning a machine that uses single serving beverage filter cartridges.

Preferably the liquid absorbing material is cotton and the wetting liquid is vinegar, such as apple vinegar. The container has an open top closed by a cover and has a bottom. Both the open top and the cover are punctured to form an inlet and an outlet to allow the heated water to pass through to heat the vinegar and mix with it for cleaning a machine that uses single serving beverage filter cartridges.
