Glen (Director): 0481 067 072Scale that appears on shower screens mainly, but also other glass, is often known as calcium scale. The reality is a little different. The scale appears to be a matrix of calcium and silica, so where there is a lot of silica in the water, cleaning is almost impossible, as silica is relatively inert.
PlatinumKleen contains a soft abrasive, and a safe powdered acid . The abrasive exposes the matrix, allowing the active ingredient to attack the calcium component, and at this stage the silica simply collapses.
"PlatinumKleen” is a non abrasive powder that will not damage glass when used according to directions.
The product works just as well on marine glass, glass pool fencing, glass balconies which scales regularly due to continually wetting and drying, again, no problem.
