Learn the best way to clean and maintain your coffee dripper for a fresh-tasting pour over every time, including daily rinses and deep cleaning tips.

Quick Answer

Rinse your coffee dripper with hot water after each brew, and give it a deeper clean weekly using mild soap or a baking soda paste to remove coffee oils and stains.

Why Regular Cleaning Matters

Coffee oils and residue build up on your dripper over time, which can make your coffee taste bitter or stale. Even if you use paper filters, oils can cling to the surface and affect the flavor of your next brew.

Glass drippers like the CARAT model are heat-resistant and dishwasher-safe, but hand washing is gentler and helps you spot any stubborn stains early.

Dealing with Stubborn Stains

For brown stains that don't come off with regular washing, make a paste of baking soda and water and gently scrub with a soft sponge. Avoid abrasive cleaners or scouring pads, as they can scratch the glass and create hiding spots for residue.

If your dripper has silicone parts, check the manufacturer's instructions—some silicone seals can be removed for separate cleaning.

Step-by-Step Cleaning Routine

Rinse after each brew: Immediately after brewing, rinse the dripper with hot water to remove coffee grounds and oils. This prevents buildup and makes deep cleaning easier. Don't let coffee residue dry on the dripper—it becomes harder to remove later.
Wash weekly with mild soap: Once a week, wash the dripper with warm water and a mild dish soap using a soft sponge. Pay attention to the grooves and edges where oils can hide. Avoid abrasive scrubbers that can scratch the surface.
Deep clean monthly: If you notice stains or a lingering coffee odor, make a paste of baking soda and water and gently scrub the interior. Rinse thoroughly with hot water. Check for any remaining residue before drying to ensure it's fully clean.
Dry completely before storing: After cleaning, shake off excess water and let the dripper air dry completely on a drying rack. Storing it while damp can promote mold or mildew. Ensure the dripper is fully dry to keep it fresh for your next brew.
