- Mixing baking soda with water forms a paste that can be used to scrub the coffee pot and filter basket, effectively removing any coffee oils or residues.
Combining vinegar and baking soda:
- By combining vinegar and baking soda, you create a fizzing reaction that helps to dislodge particles and clean tight areas in the machine. However, it’s essential to use them separately rather than mixing them together in the machine, as this can lead to an ineffective cleaning process.
Cleaning steps using vinegar and baking soda:
- Fill the water reservoir with equal parts white vinegar and water.
- Run a complete brewing cycle, allowing the vinegar solution to clean the internal components.
- After the cycle, turn off the machine and let the solution sit for about 15-30 minutes.
- Rinse the reservoir thoroughly with water to remove vinegar residues.
- Prepare a paste of baking soda and water, then scrub the coffee pot and filter basket.
- Run fresh water through the brewing cycle twice to ensure all residues are washed away.
Regular use of vinegar and baking soda is an inexpensive and environmentally friendly method to maintain coffee machines.
