NEED A DIFFERENT ROUTE?
Using a coffee machine or kettle instead?
For coffee machines and dishwashers, use DescaleX. For kettles and food-contact appliances, use DescaleX Bio.
GOOD TO KNOW
Do not use within 24 hours of a bleach cycle (chlorine gas risk).
Do not mix with detergent or any other cleaner.
Run washing-machine descales on an empty drum: longest cycle, normal water (1 sachet front load, 2 top load), then one rinse cycle.
Switch off and fully rinse geysers and boilers before returning them to regular use.
Immersion rods must be unplugged, cold, and rinsed before reuse.
