At this time of year, with the mix of rain and sun water spots are a common hazard
They may seem like a minor inconvenience, but they can lead to significant damage to your car’s paintwork. Here’s our advice on how to keep them to a minimum and maintain a glossy appearance.
Types and causes
Water spots are essentially residues of minerals, such as calcium and magnesium, that remain on the paintwork after the water has evaporated from your car’s surface. These spots are typically caused by rainwater, hard water from sprinklers, car washes and even early morning dew.
If left untreated, these can cause long-term damage to your vehicle’s appearance and value.
- Hard Water: Water with high mineral content is a major contributor. Washing your car with hard water can lead to significant water spot issues.
- Rainwater: Acid rain or rain containing pollutants can leave behind more aggressive residues.
- Sunlight: Water spots can become more severe when the car is exposed to direct sunlight, as the heat can bake the minerals into the paint.
- Improper Drying: Not drying your car properly after washing can result in water spots forming as the water evaporates.
Points to remember
Drying: Choose a shady, cooler time of day to wash your car. OUT of direct sunlight. Always dry your car with a microfiber towel after washing to prevent water from dwelling, evaporating and leaving spots.
Regular Washing: Wash your car regularly with soft water to reduce mineral deposits. Where possible, use filtered water or a valeter who carries purified water. Check out our washing guide for tips. https://surreydetailing.co.uk/2024/03/05/vehicle-maintenance-guide/
