Care and Handling - Handle like you would other kitchen equipment, but avoid detergents. After brew is complete, remove grounds from filter. Do not allow grounds to remain in filter longer than is necessary to fully drain. Evert filter and brush away most of remaining coffee grounds. Rinse filter well, wring out excess water, dip in a preferred sanitizing solution, wring it out again, and hang to dry.
With time oils will build up in the filters. The oils may be removed by boiling in fresh water. This is also an alternative method for sanitization. Sanitize in the same manner when cross contamination is suspected. Allow filters to dry thoroughly between brews.
