Cleaning

1. After brewing, remove the used coffee grounds as soon as possible. This helps reduce thermal stress on the filter fibers. Caution: the filter may still be hot.
2. Collect used coffee grounds in a separate container. They can be reused as natural fertilizer.
3. Rinse the filter immediately with cold water and allow it to air dry. The filter fibers do not absorb water and dry quickly.
4. Depending on grind size and usage, a deeper cleaning is recommended every 3–5 uses.
5. Use a mild dishwashing detergent. Avoid detergents with dyes, pigments, or added fragrances, as they may affect coffee aroma. Hand sanitizers should not come into contact with the filter.
6. Choose environmentally responsible detergents made with natural active ingredients and without added fragrances or dyes.
7. Apply a small drop of detergent to the wet filter and gently clean for a few seconds.
8. Rinse thoroughly to remove all detergent and coffee residue.
9. The Precise Brew® filter is now clean and ready to be reused.
