New Vehicle Washing Schedule for Paint Protection
Introduction

The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere,
which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these
contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the
hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching
of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface
evaporate, the concentration strength of the acid increases, causing deeper and more rapid
damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as
direct sun heat increases.
It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after
receipt at the dealership prior to the first sale. In areas known for high frequency and/or
concentration of acid rain (see Figure 1), frequent vehicle washing during high heat or humidity
periods will minimize the potential for paint damage caused by acid rain. It is further recommended
that either reverse osmosis or deionized water be used to prevent water spotting.

in high frequency and/or concentration areas of acid rain.
NOTICE

Damage to paint can start within minutes AFTER contact under these conditions.

NOTE
Review local weather on an app or website to check rain acidity levels after precipitation.

General Weather Conditions Ambient Temperature Washing Frequency

•

For temperatures between 60° – 85°F (15.5° – 29°C), the recommendation is a minimum of
once per week.

•

For temperatures above 86°F (30°C), the recommendation is a minimum of twice per week.

Rain, Heavy Dew, or Fog Conditions Ambient Temperature Washing Frequency
