How to dry your car without water spots
Most ‘spots’ are minerals left behind when rinse water evaporates on warm paint.
Two things matter most
- How fast water evaporates (sun, heat, wind).
- How much mineral is in the water (hard water = more risk).
Practical drying steps
- Dry top-down. Use a large microfibre drying towel.
- Don’t “rub dry” — blot/drag gently to reduce swirls.
- Open doors/boot briefly to catch drips before they run down clean paint.
If the forecast is hot and still, aim for shade. If it’s breezy and mild, drying becomes much easier.
