About Us

Diamond Shine Has Only One Focus:
Car Wash Chemistry.

We pride ourselves on our total commitment to the industry. We do not let anything else distract that direction. Diamond Shine is constantly developing new and innovative products and resources to make washing cars easier and more profitable.


Our manufacturing expertise started in 1944 as a local supplier for general cleaning products. Over the years, the company expanded into the laundry and ware washing industry. We serviced hundreds of restaurants and hospitals in Northeast Ohio.

In 1986, Diamond Shine was formed to service the car wash industry. Since that time, Diamond Shine has grown into the premier supplier in the industry. We service regions across North America and Internationally.

In 2003, we decided to focus solely on the car wash industry. Our other division was sold. Car wash chemistry is what we do now and who we are.

October 2017 marked an exciting change! Diamond Shine was acquired by the world’s largest manufacturer of conveyorized car wash equipment, Sonny’s Enterprises, bringing industry leading chemistry to their full suite of car wash offerings!
