56 results about "Water spot" patented technology

A water spot is an area of dried mineral deposits left on a surface after being allowed to air dry. Water quality, specifically the amount and type of minerals in the local water supply as measured by the total suspended solids or TSS test and other mineral levels such as sodium level, has a big effect on how severe water spots can be, for example on an automobile or dishes. Water spots can be avoided by drying after washing using a "shammy" cloth or towel for a car and a good drying cycle in a dishwasher, or by manual drying or good drainage after manually washing dishes.
