Descaling your coffee machine with amidosulfonic acid – this is how it's done correctly

A well-maintained coffee machine is the foundation for aromatic coffee enjoyment. To ensure your machine's long-lasting reliability, you should descale it regularly – ideally with an effective and gentle descaler . In this article, we'll show you why sulfamic acid is the best choice and how you can easily maintain cleanliness yourself with the SUPER CLEAN descaler .

Why descaling your coffee machine is so important

Hard water causes residues to build up in your coffee machine over time – especially in the pipes, heating elements, and nozzles. This not only leads to poorer coffee taste , but also to higher energy consumption and a shortened lifespan of the machine.
Regular descaling ensures:

• consistently good taste
• more efficient energy consumption
• Protection against damage to the device
• hygienic coffee preparation

Amidosulfonic acid - the insider tip against limescale

What is sulfamic acid?

Amidosulfonic acid , also known as sulfamic acid, is a highly effective substance for removing limescale. Compared to vinegar or citric acid, it works more efficiently, faster, and is gentler on materials —perfect for delicate components in coffee machines.

The advantages at a glance:

• Effective limescale removal: Removes even stubborn deposits thoroughly and quickly.
• Gentle on materials: Does not attack rubber seals or plastic parts.
• Odorless: No unpleasant aftertaste or vinegar smell.
• Environmentally friendly: Biodegradable and therefore significantly more environmentally friendly than many chemical alternatives.
• By extending the lifespan of your machine and avoiding the use of aggressive cleaning agents, you are also contributing to environmental protection.

Many people resort to household remedies like vinegar or citric acid – but these have significant disadvantages : Vinegar attacks delicate seals and often leaves an unpleasant odor . Citric acid can combine with limescale when heated, forming hard-to-dissolve deposits (calcium citrate). Descaling tablets often contain mixtures that aren't always effective enough. Amidosulfonic acid scores points here with its fast action, material compatibility, and odor neutrality – ideal for sensitive coffee machines.

This is how descaling works with the Super Clean Descaler

1. Preparation

   • Turn off the machine and let it cool down.
   • Removable parts can remain in the machine.
   • Then switch the machine back on and prepare the descaling process.

2. Prepare descaling solution

   • Mix 100 ml of SUPER CLEAN descaler with 500 ml of water and pour the solution into the water tank.

3. Start descaling program

   • Start the cleaning or descaling program and let the solution run through completely.

4. Rinse

   • Empty the tank and rinse it with clean water.
   • Start the cycle again – this time with only water.

Tip: As long as the descaling solution is red , it can be reused. When it turns orange , its effectiveness is exhausted.

Extra tips for coffee machine care

• Descale regularly – depending on water hardness, approximately every 4–6 weeks.
• Always use appropriate descaling agents – vinegar or pure citric acid can damage seals.
• Also clean the water tank and brewing unit regularly with clean water.
• For fully automatic machines: Also pay attention to cleaning programs and milk system care.

Notes for different machine types

Not every coffee machine is designed the same, so the descaling process may vary slightly depending on the machine. Here's an overview of what to look out for:

• Fully automatic coffee machines usually have a built-in descaling program. Follow the manufacturer's instructions and use only suitable descalers, such as the amidosulfonic acid-based SUPER CLEAN descaler.
• Pod and capsule machines can usually be rinsed at the touch of a button or by repeatedly turning them on. Our descaling solution also helps to thoroughly clean the piping system.
• Filter coffee machines don't have a special descaling program; the solution simply runs through the normal brewing process like water. Rinse thoroughly with clean water afterward.
• Portafilter machines should be descaled manually on a regular basis – especially the pipes and the boiler.

Tip: Always read the operating instructions for your machine – some manufacturers provide exact recommendations for quantities, mixing ratios or exposure times.

Conclusion

Sulfamic acid is the ideal descaler for modern coffee machines—effective against limescale, gentle on components, and environmentally friendly. Combined with the SUPER CLEAN descaler, you get a complete, worry-free package for your coffee care needs.
This way, your coffee stays aromatic and your machine functions for a long time – with minimal effort and maximum results.
