How to clean espresso machine parts comes down to a simple schedule: rinse after every shot, purge the steam wand after every milk drink, backflush about monthly and descale every 2 to 3 months. Breville’s own tutorial for the Barista Express uses one descaler packet in 34 oz of warm water.
Cleaning matters for hard-water homes. More George, a YouTuber who has used a Barista Express for four years, recommends filtering hard tap water and keeping up with the cleaning cycle.
Below are the schedule, step-by-step descaling for the Barista Express and tips for other machines. Your manual has the final word.

| When | Task | Why |
|---|---|---|
| After every shot | Knock out the puck, rinse the basket, flush the group head | Old grounds turn bitter and clog screens |
| After every milk drink | Purge and wipe the steam wand | Dried milk blocks the tip |
| Daily or weekly | Empty and wash the drip tray and tank | Prevents mold and odors |
| When the machine prompts you or monthly | Backflush with a cleaning tablet (machines with a cleaning disc, like the Barista Express) | Removes coffee oils |
| Every 2–3 months or when the light comes on | Descale | Mineral scale blocks water paths |
| Every 2 months (if fitted) | Replace the water filter | Protects against scale |
These are general guidelines. Always follow your machine’s manual, since intervals depend on your water hardness.
How to Descale a Breville Barista Express (Step by Step)
- Empty the drip tray and tank, and remove the water filter
- Mix descaler and water per the descaler label (Breville’s video: one packet in 34 oz of warm water)
- With the machine off, hold the 2-cup and power buttons to enter descale mode
- Place a large container (Breville suggests 68 oz) under the group head and wand
- Press 1-cup to descale the group head, then turn the dial to run the steam wand and hot water

- Rinse the tank, fill with fresh water and run the same steps to flush

- Breville’s official tutorial (Barista Express): remove the water filter, dissolve one descaler packet in 34 oz of warm water, put a 68 oz container under the group head and steam wand, and follow the button sequence before rinsing with a full tank of fresh water.
- The YouTube channel Clean That Up (Barista Express): descale by mixing 4 oz of descaler with 34 oz of water, entering descale mode (hold 2-cup + power), running the group head, hot water and steam wand, then rinsing with fresh water.

Frequently Asked Questions
Can I clean my espresso machine with vinegar?
Many makers, including Breville in its tutorial, use their own descaler. Check your manual before using vinegar, since some makers advise against it.
How often should I descale?
Follow your machine’s indicator or manual; it depends on water hardness. Filtered or softened water helps.
What is backflushing?
Running water and a cleaning tablet through the group head with a blind disc, which removes coffee oils. Clean That Up shows a 5–6 minute cycle on the Barista Express.
How do I clean the steam wand?
Purge it right after steaming and wipe it with a damp cloth. Use the cleaning pin if the tip clogs.
