Myth #1

Myths of Cleaning Myth 1 of 8: Water is Obviously “Cheaper” than Solvents Regular city water alone won’t clean anything. It needs surfactants and detergents that lower surface tension and remove soils. These are consumed during cleaning and need replenishing. Higher temperatures are needed to activate cleaning chemistry, which is important for ensuring good wetting… Read more »

Myth #2

Myths of Cleaning Myth 2 of 8: Aqueous Systems Can’t Be Used in Critical Cleaning First, let’s be clear that “critical cleaning” has a very specific meaning.
