Add water to kettle until approximately ¾ full. Add the premeasured required amount of Kettle Descaler to the cold water. For best results boil the kettle once. Allow a minute for boiling water to completely settle (stop boiling) before discarding contents down the drain. (For very heavy build-up of scale a second application may be required.) to rinse correctly, refill the kettle to full with clean water and re-boil. Repeat this rinsing process 3-4 times, each time using fresh clean water. This ensure the kettle is fully rinsed clean before use. Do not leave kettle unattended at any point, until very last rinse. For taps and appliances: IMPORTANT: Ensure safety glass and a new pair gloves are warn before use. Using a small brush, carefully apply Appliance Descaler to the surface and allow to stand before rinsing with clean water. Wipe off any remaining water after rinsing with a clean cloth. For stubborn stains or scale marks, gently agitate if necessary using the small brush. Do not leave neat product on any Chrome surfaces. DO NOT USE ON MARBLE OR ENAMELLED SURFACE
