Myth #1

Myths of Cleaning Myth 1 of 8: Water is Obviously “Cheaper” than Solvents Regular city water alone won’t clean anything.

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.
