  1. So essentially the softwash process is achieved through a process of oxidation and microbial breakdown...So does it matter whether the oxidation process is achieved through a solution of SH,Cl, or Calcium Hypochlorite. Calcium Hypochlorite having a higher available level of chlorine seems to be the most efficient base component in a softwash solution (if diluted correctly) and especially in a High Test Hypochlorite form (like that of pool shock products). All of these products will be rendered inert when exposed to harsh temperatures so there is no extended cleaning life, however, they will leave behind there sodium chloride (salt) base compound, and with the Calcium Hypochlorite having larger amounts of available chlorine it will in turn have higher levels of salt biproduct. Other then a little more time spent on a rinse down of the Calcium Hypochlorite to avoid rain runoff concentrations killing plants, i am failing to figure out why this is not the base component for a softwash dilution, when it is stronger and can be diluted down to safe levels for vinyl and paint, it is more cost effective, and it is more resistant to temperature and UV eposure. HTH or High Test Hypochlorite typically has 65-70% available Chlorine Generic Calcium Hypochlorite contains approx 25-30% available Chlorine http://www.who.int/water_sanitation_health/hygiene/emergencies/fs2_19.pdf
