The leading ingredients in building grime are:
1. Micro-particles of tire rubber (organic)
2. Soot from the exhaust of cars and factories (organic)
3. Silicates (inorganic sand and soil)
4. In some climates, black mold (organic)
High pressure water is required to clean most outside surfaces because the organic contaminants form glue-like bonds that are very hard to break.
PURETi oxidizes (breaks down) the organic particles at the molecular level before they can stick to the surface.
PURETi does not break down sand, but the sand rinses easily because there is no “glueâ€ to hold it in place. 
Stop power washing and start “Sun Washingâ€ with PURETi
Apply PURETi to outside surfaces that need to stay clean to reap the following benefits:
Hard ROI
Reduced frequency and intensity of pressure washing
Window cleaning can be done half as often, and with half the effort
Solar panel output and solar reflectance can be increased
Soft ROI
Measurable contribution to corporate sustainability goals
Brand Enhancement - buildings look great between cleanings
