For any chemical company to maintain pricing levels for their products with the current increases in raw materials due to the increase in oil prices in most cases would require either reformulation of their products or decreasing activity of the products.
Most of the recent car wash chemical price increases were in the 5% range although some of the major brands increases total closer to 10% for the year. Anyone knows that is not even close to the percentage increases we have seen due to fuel costs. In my area gas prices alone have gone up well over a dollar from last year at this time representing more than a 40% increase. Other staples like bread, meat, fruit, vegetables, eggs and milk have experienced similar increases. If and when oil prices go down and fuel prices decrease they never seem to go back to their original level. To suggest that chemical companies decrease their price if prices of oil goes down is not reasonable.
