Where are the Type A areas of California? Currently, AWWF sold in Type A areas is limited to 25% VOC, meaning pre-mixed AWWF will have no more than 25% VOC, and dilutable AWWF, when properly diluted, will contain no more than 25% VOC.Īll other areas of California (non-Type A areas) are limited to selling 1% VOC in pre-mixed AWWF. The regulation for this type is that it must clearly state on the front label that it is a concentrate, or dilutable, and on the back it must have clear instructions of how to dilute it to Type A area specifications and to non-Type A area specifications. It is available anywhere in California, and is most often found at automotive supply stores and service stations.įor further clarification, pre-mixed AWWF may be sold in containers greater than one quart, but less than 10 gallons. Dilutable AWWF is sold in containers that are one quart or less, or 10 gallons or more. The regulation for this type is 25% VOC content, and it is only allowed to be sold in Type A areas of California.ĭilutable, or Concentrated AWWF, typically sold in 1-quart size containers. Pre-mixed AWWF that is typically sold in gallon-size containers labeled 'winter formula', 'protects to zero degrees,' or something similar. Pre-mixed AWWF that is typically sold in gallon-size containers, labeled 'summer formula' or 'protects to +32 degrees.' The regulation for this type is 1% VOC content, and it can be sold anywhere in California. What kinds of AWWF are affected by the Regulation? The California Consumer Products Regulation establishes limits on the VOC content of AWWF. Reducing the amount of VOCs emitted into the atmosphere from consumer products is imperative to California's commitment to cleaner air, to protect public health and the environment. In most areas of California, milder temperatures do not necessitate the use of VOCs for AWWF to wet and clean vehicle windshields.

Why are VOCs in Automotive Windshield Washer Fluid Regulated in California?īefore it was regulated in 1993, automotive windshield washer fluid (AWWF) was a very large source of pollution in California's cities. AWWF contained high levels of volatile organic compounds (VOCs) which are a component of ground-level ozone formation, and one of the main pollutants that compose smog. VOCs are used in AWWF as an anti-freeze which reduces the temperature the fluid will freeze in cold weather.
