How to Clean Your Coffee Gear After the Holidays (Without Ruining Anything)

The holidays are over. You've made approximately 47 lattes, your espresso machine has seen things, and there's dried milk somewhere you can't quite identify. It's time to clean.

Here's how to deep-clean your coffee gear without breaking anything, ruining the finish, or voiding the warranty.

Why This Matters

Coffee oils, milk residue, and mineral buildup don't just make your machine look gross—they make your coffee taste bad. A dirty machine = bitter, off-tasting coffee. Plus, buildup can clog parts and shorten the lifespan of your equipment.

Think of this as a post-holiday reset. Clean gear = better coffee in the new year.

Espresso Machine Deep Clean

What you need:

• Espresso machine cleaning tablets or powder
• A small brush (most machines come with one)
• A microfiber cloth
• Descaling solution (if your machine needs it)

Step 1: Backflush the group head (if your machine has this feature)
Machines like the Gevi Commercial Espresso Maker, Gevi 20 Bar, or CASABREWS 5418 PRO have backflush capabilities. Insert a blind basket (no holes), add a cleaning tablet, and run the brew cycle for 10 seconds. Repeat 3–4 times, then run water through to rinse.

Step 2: Clean the portafilter and basket
Soak them in hot water with a cleaning tablet for 15–20 minutes. Scrub with a brush to remove coffee oils. Rinse thoroughly.

Step 3: Wipe down the steam wand
This is where dried milk lives. Wipe it with a damp cloth, then purge steam through it to clear any internal buildup. If it's really bad, soak the tip in hot water for 10 minutes, then scrub.

Step 4: Clean the drip tray and water reservoir
Empty, wash with soap and water, dry completely before reassembling.

Step 5: Descale (if needed)
If your machine has a descale light or it's been 2–3 months, run a descaling cycle. Follow the manufacturer's instructions. Machines like the Bosch 800 Series have automatic descaling programs.

Nespresso Machine Clean

What you need:

• Nespresso descaling kit (or citric acid solution)
• A damp cloth

Step 1: Run a descaling cycle
For machines like the Nespresso Vertuo Plus or Vertuo Pop+, follow the descaling instructions in the manual. It usually takes 15–20 minutes.

Step 2: Clean the capsule container and drip tray
Wash with soap and water, dry completely.

Step 3: Wipe down the exterior
Use a damp microfiber cloth. Don't use abrasive cleaners—they'll scratch the finish.

Step 4: Clean the Aeroccino (if you have one)
Rinse immediately after each use (you should already be doing this). For a deep clean, fill with warm water and a drop of dish soap, run a cycle, then rinse thoroughly.

French Press Clean

What you need:

• Dish soap
• A bottle brush
• Baking soda (for stubborn stains)

Step 1: Disassemble completely
Take apart the plunger, filter screens, and glass carafe.

Step 2: Scrub everything
Use a bottle brush and dish soap to scrub the inside of the carafe. Pay attention to the filter screens—coffee oils love to hide there.

Step 3: Remove stains
If your French press has brown stains, make a paste with baking soda and water, scrub gently, then rinse.

Step 4: Dry completely before reassembling
Water spots are annoying. Dry everything with a clean towel.

Milk Frother Clean

Electric frothers (like Aeroccino):
Rinse immediately after use. For deep cleaning, fill with warm water and a drop of dish soap, run a cycle, rinse thoroughly. Never submerge the base in water.

Handheld frothers:
Rinse the whisk under hot water immediately after use. If milk has dried on it, soak in warm soapy water for 10 minutes, then rinse.

Steam wands:
Wipe with a damp cloth after every use. Purge steam through it to clear internal buildup. If the tip is clogged, soak it in hot water for 10 minutes, then use a pin to clear the holes.

Grinder Clean (If You Have One)

What you need:

• A small brush
• Grinder cleaning tablets (optional)

Step 1: Empty the hopper and grind chamber
Remove any leftover beans.

Step 2: Brush out coffee dust
Use a small brush to clean the burrs and grind chamber. Don't use water—it'll cause the coffee oils to gum up.

Step 3: Run grinder cleaning tablets (optional)
If your Gevi Espresso Machine with Grinder or Gevi 10-Cup with Built-in Grinder has been heavily used, run cleaning tablets through to absorb oils.

What NOT to Do

• Don't use vinegar in espresso machines: It can damage internal seals. Use proper descaling solution.
• Don't put non-dishwasher-safe parts in the dishwasher: Check your manual first.
• Don't use abrasive cleaners: They'll scratch stainless steel and glass.
• Don't skip drying: Water spots and mineral buildup happen when you leave things wet.

The Bottom Line

A clean machine makes better coffee. Spend 30 minutes doing a deep clean now, and your Maestri House Espresso Machine, Nespresso VertuoPlus, or French press will thank you with better-tasting coffee all year.

Now go clean your gear. Future you will appreciate it.
