How often should I descale my Karcher pressure washer?

The frequency of descaling a Karcher pressure washer largely depends on the water hardness in your area and how often the unit is used. Generally, it is advisable to descale the pressure washer every three to six months if you are using it frequently, especially in areas with hard water. Hard water can lead to the buildup of limescale, which may affect the performance and longevity of the machine. In contrast, if you live in an area with soft water and use the pressure washer infrequently, you may be able to descale it less often, possibly once a year. To ensure optimal performance, always refer to the specific guidelines provided in the user manual for your particular Karcher model, as different models may have varying requirements for maintenance. For further details, it is worth checking the manufacturer's website for any additional tips or advice on maintenance and descaling.
