Identify the appliance and its care procedure
Check the model manual for any maintenance alert, approved cleaner, amount, temperature and rinse cycle. Kettles, coffee makers, dishwashers, washing machines and humidifiers are not interchangeable.
Use only an approved descaler
A product designed for one appliance may damage another. Follow the label and manual, and avoid adding vinegar, citric acid, bleach, baking soda or another product unless the manufacturer explicitly allows it.
Keep electrical and moving parts safe
Switch off or unplug the appliance as the instructions direct. Do not immerse bases, spray controls, remove filters or dismantle parts unless the manual describes a safe user-maintenance step.
Distinguish scale from a fault
Slow performance, leaks, error codes, unusual noise or persistent residue may indicate maintenance or repair beyond descaling. Stop repeated chemical treatments and ask the manufacturer or a qualified technician.
Choose a compatible cleaning scope
Routine cleaning of appliance exteriors and surrounding surfaces differs from internal descaling or repair. If requesting help, confirm exactly which appliances, methods and exclusions are included.
