NEED A DIFFERENT ROUTE?
Using a kettle, washer, or geyser instead?
For kettles and food-contact jobs, start with DescaleX Bio. For washing machines, geysers, and immersion rods, start with WashDX.
GOOD TO KNOW
Do not use on aluminium cookware or unlined brass kettles - use DescaleX Bio for kettles instead.
Empty appliance only. No grounds, dishes, or drinking water left inside.
Use gloves and keep the sachets dry until use.
