Instant coffee machines are convenient, but they need regular cleaning. Over time, mineral deposits (scale) build up inside the machine. This affects taste, performance, and lifespan. Descaling removes these deposits.
Why Descaling is Important
Better Coffee Taste
Scale contains calcium and magnesium. These minerals make coffee taste bitter or metallic. Descaling ensures pure, fresh flavor.
Improves Machine Performance
Scale clogs pipes and heating elements. This slows brewing, reduces water flow, and may cause leaks.
Extends Machine Lifespan
Scale damages internal parts. Regular descaling prevents costly repairs or replacements.
Energy Efficiency
A scaled-up heater works harder, using more electricity. Descaling keeps energy use low.
What You Need for Descalin
- Descaling Solution
- Commercial descaler (Urnex, De’Longhi, Durgol)
- Natural alternatives (white vinegar, citric acid)
- Water (for rinsing)
- Soft cloth or sponge
- Container (to catch water during the process)
Step-by-Step Descaling Guide
Step 1: Prepare the Machine
- Turn off and unplug the machine.
- Remove any coffee pods or grounds.
- Empty the water tank.
Step 2: Mix the Descaling Solution
- Commercial descaler: Follow bottle instructions (usually 1 part descaler to 1 part water).
- Vinegar method: Mix equal parts white vinegar and water.
- Citric acid method: Dissolve 2 tablespoons of citric acid in 500ml warm water.
Step 3: Fill the Water Tank
Pour the solution into the tank.
Step 4: Run a Descaling Cycle
- Plug in and turn on the machine.
- Start a brewing cycle (without coffee). Let the solution run through.
- Pause halfway (if possible) to let the solution sit for 15-20 minutes. This loosens tough scale.
- Complete the cycle.
Step 5: Rinse Thoroughly
- Empty the tank.
- Fill with fresh water.
- Run 2-3 brewing cycles to remove any descaler residue.
- Repeat if you still smell vinegar or chemicals.
Step 6: Clean External Parts
- Wipe the machine with a damp cloth.
- Clean the drip tray and removable parts with soapy water.
Step 7: Test the Machine
Brew a test cup of water (no coffee). If it tastes clean, your machine is ready.
Best Descaling Solutions
Commercial Descalers
- Pros: Fast, effective, safe for most machines.
- Cons: More expensive than natural options.
White Vinegar
- Pros: Cheap, readily available.
- Cons: Strong smell, may leave taste if not rinsed well.
Citric Acid
- Pros: Natural, no strong odor, gentle on machines.
- Cons: Less effective on heavy scale buildup.
Tips to Prevent Scale Buildup
- Use Filtered Water – Reduces mineral content.
- Descale Regularly – Don’t wait for problems.
- Empty Water Tank Daily – Stagnant water promotes scale.
- Wipe After Each Use – Prevents residue buildup.
Common Mistakes to Avoid
- Using bleach or harsh chemicals – Damages internal parts.
- Skipping rinsing – Leaves bad taste in coffee.
- Descaling too rarely – Causes permanent damage.
- Using undiluted vinegar – Too acidic, can harm seals.
Conclusion
Descaling keeps your instant coffee machine running smoothly. Follow these steps every 1-6 months, depending on water hardness. Use commercial descalers, vinegar, or citric acid. Always rinse well to avoid bad tastes. A clean machine means better coffee and longer lifespan. Take care of your machine, and it will take care of your coffee cravings!
