The use of hard water in spray preparations is very common in some parts of Australia. At Eureka! we expend a lot of effort ensuring that new products we develop for the Australian market are able to cope with hard water.

Hardness is caused by calcium and magnesium ions that are dissolved in the water. They get there when the water passes through rocks or soil that contain these ions, such as limestone. A lot of Australia’s farming land sits on such deposits and, not surprisingly, Australia have a lot of farms that have bores or even dams filled with hard water.
