Before You Start

Check the user manual for any model-specific cleaning instructions or cautions. Unplug the machine before handling internal components. Clear the area of clutter and ensure the carafe is empty. Time estimate: about 30–45 minutes. Safety note: if the machine has a leak, discontinue use and consult a professional.

Step-By-Step: How To Clean A Mr Coffee Maker

Empty the carafe and remove any used coffee grounds or filters from the basket. Wipe the exterior with a damp cloth.
Prepare the descaler solution according to the product’s instructions. Use descaling tablets for Mr Coffee maker or automatic coffee maker descaling powder as directed.
Fill the water reservoir with the descaler solution up to the indicated fill line. Do not exceed the maximum capacity.
Run a complete cleaning cycle without coffee. If your model has a dedicated cleaning setting, select it; otherwise run a standard brew cycle and pause mid-cycle to let the solution soak for 15–20 minutes.
After the cycle completes, run 2–3 full cycles with clean water to rinse the interior and remove any remaining residue.
While rinsing, use the stainless steel carafe cleaning brush for coffee maker to scrub the inside and the lid, then rinse thoroughly.
Wipe the exterior, including the control panel and warming plate, with a mild cleaner and a damp cloth. Dry with a soft towel.
Inspect the gasket and seals; if you notice buildup, use the replacement coffee maker gasket cleaning tool to gently clean around the gasket area or replace if worn.
Reassemble everything, fill the reservoir with fresh water, and run a final rinse brew to ensure no cleaning solution remains.
Test with a pot of plain water to verify there are no flavors carried over into coffee.
Regular maintenance: run a quick rinse weekly and a deep descale every 1–3 months based on water hardness and usage.
