To deep clean and maintain a coffee maker, regularly descale with vinegar, clean removable parts, and run water cycles to remove residue.
A clean coffee maker is essential for brewing great-tasting coffee. Over time, mineral deposits, oils, and bacteria can build up, affecting both flavor and performance. This guide will show you how to deep clean and maintain your coffee maker properly.
Why Cleaning Your Coffee Maker Matters
Your coffee maker accumulates more than just coffee stains. Studies show coffee reservoirs rank among the germiest spots in homes. Mold, yeast, and bacteria thrive in the warm, moist environment. Regular cleaning prevents health risks and ensures your coffee tastes its best.
Signs Your Coffee Maker Needs Cleaning
- Slow brewing times
- Visible mineral deposits
- Odd-tasting coffee
- Cloudy water in the carafe
- Oily residue on components

Special Considerations for Different Coffee Makers
Keurig and Single-Serve Machines
Clean the water reservoir and descale monthly. Use vinegar or Keurig’s cleaning solution. Don’t forget to clean the needle that punctures K-cups.

Backflush with cleaner weekly. Soak removable parts in vinegar solution. Clean steam wands immediately after use.
Preventing Buildup Between Cleanings

Troubleshooting Common Issues
Vinegar Smell After Cleaning
Run additional water cycles until the smell disappears. The Better Homes & Gardens cleaning guide recommends at least two rinse cycles.
Mineral Deposits Won’t Budge
Soak affected parts in undiluted vinegar overnight. Use a soft brush to scrub stubborn spots gently.
Mold or Mildew Growth
Clean with a stronger vinegar solution (3:1 vinegar to water). Consider using a bleach solution (1 tbsp bleach per gallon of water) for severe cases, followed by thorough rinsing.
