Calotherm - Calotherm Sprays

A brand with a
proud heritage.

Whilst working in a laboratory in the 1930s, our founder formulated an anti-mist spray for spectacles, and Calotherm was born. As the brand has evolved, so the line-up of products and the breadth of applications has grown. But all with the same underlying purpose and character – applying scientific precision to the cleaning of premium shiny surfaces.
