Dilute with fresh, clean water according to the level of descaling action required.
Use undiluted for the heaviest deposits, or dilute up to 1:80 for light duty descaling.
Leave in contact with surfaces for at least 1 hour or overnight.
For appliances such as coffee machines and steam irons, fill the water compartment with solution prepared to an appropriate dilution and prime by drawing a small amount of solution through the system before leaving to work.
All appliances with food contact surfaces should be thoroughly rinsed with clean water after using the descaler.
