Frequently Asked Questions
Yes, white vinegar (diluted 1:1 with water) can work as a natural descaler. However, commercial descalers are more effective, work faster, and don’t leave a strong smell. Products like the IMPRESA or Essential Values descalers are specifically formulated for better results.
Signs include: visible white deposits, longer boiling times, unusual noises during heating, floating particles in boiled water, or reduced water capacity due to buildup. If you notice any of these, it’s time to descale.
Most descalers are safe for stainless steel, glass, and plastic kettles. However, always check the product label and your kettle’s manual. Natural citric acid-based descalers like Essential Values are the safest option for all materials.
Descalers primarily remove mineral deposits (limescale). For other stains or discoloration, you may need specific cleaning methods. Check our kettle cleaning guide for comprehensive stain removal techniques.
