The Problem with Tap Water


Even treated tap water contains microscopic contaminants:

Calcium

Magnesium

Silica

These minerals remain on your car after rinsing and create visible water spots, dull finishes, and micro-etching. Over time, they break down ceramic coatings, degrade paint protection films, and ruin surface clarity—especially on dark-colored or high-gloss finishes.
