According to an article in the Detroit News it appears that high gas prices have caused drivers to pinch their pennies and have their cars washed less frequently. Car wash owners in the Detroit area believe their revenues are 30 percent lower than normal. I never realized it, but winter is when car washes make enough money to get them through the slower parts of the year. When I think on it, it makes sense that winter is their busiest time with all of the grime on cars from winter driving. The decline in revenue has caused many car wash owners to raise their prices in hopes to stay in business. The Detroit News has a poll going on that lets you place your vote on whether or not you are getting your car washed less this winter.
