TIPS
Should I wash my car before or after it rains?
You should wash your vehicle when it is dirty, regardless if it is before or after rain. When it is dirty, your vehicles surface is holding all kinds of dirt particles, contaminants and road grime. Mix this with water and you have cement. Whatever is water soluble mixes with other particles and new paint problems are born. Rain WILL NOT clean these particles off of your car.
Why do I need to wash my car after it rains or Snows?
This is a critical time to protect your vehicle's finish. Pollutants such as sulfuric and nitric acids from automobile, truck and factory exhaust become trapped in the raindrops or snow flakes that settle on your vehicle. The sun will evaporate the water and leave behind concentrated acid that can damage your vehicle's finish.
What is the layer of film that covers my vehicle between washes?
What you are referring to are black particles that come from areas of heavy traffic. They are gritty, abrasive substances coming off tires as they wear. Also, chemicals from diesel smoke and other emissions in the atmosphere will settle on your vehicle's surfaces. In the Wellington City area we have fallout from Jet exhaust. If this residue isn't removed immediately, permanent damage to the finish can result.
Isnt rain the best wash for my car?
NO! Rain and snow contain acids that eat away at the paint and finish of vehicles. After acid rain falls on a vehicle, the water evaporates, but the acid remains. Concentrated by sunlight, this acid can become so strong that it will eat through the finish, ruining the vehicle's paint and appearance.
