To prolong the life of your new kettle descaling should be carried out on a regular basis. The frequency required will depend on your water hardness.
If you have particularly hard water (see the map on the right) we would recommend the kettle is descaled every month. For very soft water areas we would recommend that you descale your kettle every three months.
Care should be taken with proprietary kettle descaler as these could damage the surface finish of the kettle. Please ensure you follow the instructions carefully.
If you do not want to use a proprietary descaler we would recommend a solution of one part white vinegar and two parts water. Switch the kettle on, remembering to switch it off just before the boiling point. Leave the solution in the kettle for a while, dependant on the severity of the scale inside and then empty the kettle. Refill with fresh water, boil, empty and repeat this process once more. Your kettle can now be used.
If you have missed a descale it may be worth leaving the solution overnight.
