CLEANING YOUR KETTLE
-8-
Interior Cleaning
1. To clean the inside of the kettle, use a damp cloth. Even though your kettle
includes a water filter, you still need to clean the interior and the filter regularly.
Water Filter
1. Remove the lid and lift out the water filter. Rinse the filter under running water
or use a soft brush to clean. Or when decalcifying your kettle, keep the filter
in place. Then rinse the water filter thoroughly.
2. Replace the filter by placing the front of the filter into the spout area, and then
clip into place. Figure 2
Decalcification
What is lime scale?
Lime scale is mainly calcium carbonate, a harmless, naturally occurring mineral
found in most water supplies. “Hard” water contains more of this mineral than
“soft water”. When the water is heated, the minerals in the water solidify,
making the water appear cloudy. These minerals form a thin film on the walls,
element and on the surface of the water. The water may look as though it has
white colored pieces of plastic floating on the surface. On traditional kettle
heating elements, scale forms a hard white “crust” that adversely affects
performance and reduces the life of the heating element.
1. Regular decalcification of the interior will improve the performance of the
kettle. If the kettle is not decalcified regularly, the lime scale build-up may result
in the following:
a) The kettle may switch on and off during use or may switch off before
boiling.
b) The kettle may take longer to boil water than normal.
c) The heating element may become damaged.
2. When lime scale starts to build-up on the interior of the kettle, we recommend
using white vinegar as follows:
a) Pour into kettle 2 oz. of white vinegar and then fill with water up to the MAX
level indicated and then boil as usual. Allow the contents to cool, and then
rinse thoroughly.
b) Do not use a concentrated solution. If the filter requires decalcification,
remove the filter and place into the white vinegar solution in the kettle.
3. NOTE: To prevent lime scale build-up, use filtered water to fill your kettle.
