FAQ

Coffee & Bakeware — FAQ

How often should I descale?

Most manufacturers recommend descaling every 3 months. If you live in a hard water area, you may need to descale monthly.

Can I use vinegar instead?

While vinegar is a common household cleaner, it can damage internal seals and leave a persistent odor. Dedicated descalers are safer for internal components.

Is this safe for my machine?

Always check your manual to see if the product is compatible with your specific model. Most solutions are safe for aluminum and plastic parts when used correctly.

What if my machine is badly clogged?

You may need to run a double-strength cycle or repeat the process. If flow remains low, professional servicing might be required.

Does it affect coffee taste?

High-quality descalers are designed to rinse out completely. Proper flushing ensures your next cup tastes clean and fresh.

Are tablets better than liquids?

Tablets are often more convenient for storage and travel. Liquids are generally preferred for deep cleaning complex internal boiler systems.
