This post isn’t about scrubbing harder or jumping straight to polishing.
It’s about identifying what kind of water spot you have — and choosing the safest removal method that fixes the problem without removing unnecessary paint.

Key Takeaways

  • Not all water spots are the same.
  • Mineral deposits cause permanent damage if ignored.
  • Chemical removal is safer than polishing first.
  • Over-polishing removes valuable clear coat.
  • Proper drying prevents future spots.

The Real Cause of Water Spots

Water spots are caused by minerals left behind as water evaporates.

Common sources include:

  • Hard tap water
  • Sprinklers
  • Rain mixed with pollution
  • Improper drying

Once minerals bond to the surface, washing alone won’t remove them.
