Importance of Regular Espresso Machine Cleaning

Espresso machines require consistent cleaning to:
✔ Preserve flavour – Old coffee oils turn rancid, making espresso taste bitter.
✔ Prevent clogs – Grounds and residue can block water flow.
✔ Extend machine life – Mineral build up (scale) damages internal components.
✔ Ensure hygiene – Bacteria and mould can grow in damp coffee residue.

Neglecting cleaning leads to poor extraction, inconsistent shots, and costly repairs.

Common Coffee Residue and Its Impact on Flavour

Several types of build up affect your machine:

1. Coffee Oils

• Sticky residue from espresso that clogs filters and group heads.

• Turns rancid over time, causing bitter, off-flavours.

2. Mineral Deposits (Scale)

• Hard water leaves calcium and magnesium deposits.

• Reduces heating efficiency and clogs steam wands.

3. Old Coffee Grounds

• Trapped in portafilters and grinders, leading to uneven extraction.

Can You Clean an Espresso Machine Without Coffee?

Yes! While specialty coffee-based cleaners (like Cafiza) are ideal, you can use alternatives:

1. Vinegar & Water (For Descaling)

• Mix 1:1 white vinegar and water for descaling.

• Rinse thoroughly to avoid vinegar taste.

2. Baking Soda (For Mild Cleaning)

• Helps remove light stains and odours.

• Not as strong as espresso cleaners but works in a pinch.

3. Citric Acid (For Scale Removal)

• A natural descaler that dissolves mineral build up.

⚠️ Avoid harsh chemicals (bleach, dish soap)—they can damage seals and leave bad tastes.

Best Cleaning Methods for Espresso Machines

1. Daily Cleaning

• Rinse portafilter & basket after each use.

• Wipe steam wand immediately to prevent milk build up.

• Purge group head with hot water.

2. Weekly Deep Cleaning

• Backflush with a blind basket & detergent.

• Soak portafilter & shower screen in warm, soapy water.

• Scrub steam wand with a damp cloth.

3. Monthly Descaling

• Follow manufacturer guidelines to avoid damage.
