Cleaning balls for decanters from Peugeot's Bilbo series. Tannins and limescale deposits cling stubbornly to the inside of a decanter and are nearly impossible to reach with a regular brush. Fill the decanter with warm water, drop in the balls, swirl gently and let them do the work. No cleaning products needed.
The container also doubles as a funnel and strainer: pour the balls directly from the container into the decanter and back again without spilling a drop. Rinse the balls after use and let them dry in the container before storing.
