A great cup of coffee doesn’t just depend on quality beans—it also requires clean, well-maintained equipment. Over time, coffee oils, mineral deposits, and residue build up in your gear, leading to bitter, off-tasting brews.
In this guide, you’ll learn how to properly clean and care for your coffee tools, from grinders to French presses, to ensure every cup tastes as fresh and flavorful as it should.
Why Cleaning Matters
When coffee equipment isn’t cleaned regularly, it leads to:
- Rancid oil buildup from old coffee
- Mold or bacteria growth
- Inconsistent brews
- Shorter equipment lifespan
Proper maintenance not only improves flavor—it protects your investment.
