How to Wash a Car in Direct Sun Without Water Spots

No shade? No problem. Here’s how to safely wash your car in direct sunlight without leaving behind ugly water spots.

Ideally, you’d always wash your car in the shade. But sometimes, shade isn’t an option. Whether you live in an apartment complex, have limited driveway space, or just need to wash during the day, washing in direct sun is possible—as long as you take a few key precautions.

Why Water Spots Happen

Water spots form when minerals in tap water dry on the surface before you can remove them. Sunlight speeds up evaporation, meaning spots form faster and etch deeper.

Step-by-Step: Washing in the Sun

  1. Work in sections: Don’t wash the whole car at once—wash and dry one panel at a time.
  2. Foam generously: Cover each section with The Super Soaper to add lubrication and cooling.
  3. Rinse quickly: Don’t let soap dry on the surface.
  4. Dry immediately: Use the Massive Drying Towel to blot away water before it evaporates.
  5. Add protection: Apply Tough As Shell ceramic spray to keep water from sticking.

Comparison: Shade vs Sun Washing

Longer working time Work panel by panel
Low risk of water spots High risk if not dried quickly
Relaxed process Faster pace required
Pro Tip: Keep a spray bottle of deionized or distilled water handy. If water starts to dry, mist the panel to re-wet it before drying.
