rain Damage car paint

At Auto Boss Vaughan, our experts receive questions about the elements affecting car paint. Many ask whether the rain affects the vehicle’s clear coat. The answer to this question is “It depends.” Besides watermarks, rain can result in rusting, fading, and other problems. If you wash your vehicle correctly after showering, you may protect it from hard water marks. But if you don’t wash it may result in the building up of dirt. It is harder to remove this dirt. 

In summer or spring, when rain is continuous, we suggest you wash and get it cleaned after a week. If proper hand-wash doesn’t work, use a surface cleansing mitt or a clay bar. These solutions can remove ingrained dirt from your car paint. 

Acidic rain effects 

Acid rain is a mixture of the dry and wet deposition from the atmosphere that contains a more significant amount of sulfuric and nitric acid, as defined by EPA. Sometimes it includes elements and pollutants more than usual, depending on weather patterns. 

Acidic rain has higher than average acidity and has different effects than average. It can damage paint more than normal rainfall. It has the impact of hard water spots that can damage your car paint permanently.

However, taking preventive measures can protect your car’s engine. High-quality protective coatings like ceramic coating and wax help detect the harmful effects of rain elements. 

Dirty rain 

Rain contains dirt particles and contaminants that leave mud on the vehicle’s surface that dries in the sun. Dirty precipitation usually occurs in deserts or areas with low levels of greenery. The dry mud can affect your car’s clear paint coat creating micro-scratches or may create fading effects on your car’s surface. 

The common myth about the rain 

The rainwater is supposed to be pure and can wash the car. However, the truth is far different because of the two reasons.

Rain contaminants 

Rainwater causes more damage than it helps you. In some cases, rainwater contains contaminants and pollutants from the air that cause damage to the car’s surface. The acidic rain leaves a thin layer of pollutants on your car’s surface that can harm your paint. 


Rainwater has low pressure that is not strong enough to wipe off the stains from the car’s surface. It can provide light rinses that cannot obliterate dirt and grime from your vehicle. Overall, leaving your car in the rain to get a wash for free is not a good idea. Your truck needs intense pressure to remove the contaminants and dirt from your vehicle. 

We performed a survey of what people have in their minds. 

  • People consider it a waste of time to clean up your car if it had rain on it only. They will like to wait for the next rain to wash the car.
  • Some people are concerned about water spots created by rain.
  • Washing the car before it rains can help get rid of water spots. 
  • Very few people believe rain can convert dirt into a bigger mess.
