Removing ‘Water spots’
Always start by using the least abrasive product first
1. Use a paint surface cleaner (Z-PC Fusion Dual Action Paint Cleaner or Duragloss 501)

2. Try to dissolve the alkaline-based, surface/etched mineral water deposits with one or more of the following;
a) Use a 2:1 or stronger solution of distilled water/distilled white vinegar (Acetic acid)
b) Try a 2:1 solution of distilled water/Isopropyl Alcohol (adjust ratio as required)
c) Or equal parts distilled water/distilled white vinegar/Isopropyl alcohol.

3. Clean the effected surface with Klasse All-In-One or Zaino Z-PC Fusion Dual Action Paint Cleaner
4. Use detailing clay to remove any `hard' surface granules
5. Use a machine polish (Optimum Polish, Optimum Compound) and a cutting (LC White, Orange or Yellow) foam pad (speed # 4- 5.0) to level the paint surface
6. Use the least aggressive polish/foam pad first, if this doesn’t remove the problem step-up to a more aggressive polish / foam pad set-up
7. Wet-sand with 2000, 2500 or 3000 grit finishing paper
