Cintas Corporation (/ˈsɪntɑːz/) is an American corporation headquartered in Mason, Ohio which provides a range of products and services to businesses including uniforms, mats, mops, cleaning and restroom supplies, first aid and safety products, fire extinguishers and testing, and safety courses.

In the early 1940s, Doc's son Hershell, took over and replaced the old rags with shop towels, becoming a service company.

[10] Hershell's son, Richard "Dick" Farmer, joined the family business in 1957 after graduating from Miami University in Oxford, Ohio.

Dick worked with Celanese Corporation, Graniteville, and Redkap to develop a 65/35 Polycotton fabric blend.

The court ruled that the labor union violated the privacy of thousands of Cintas employees in Pennsylvania, by illegally obtaining their license plate numbers in order to access their home addresses and other personal information.

Both unions and several Members of Congress called for stricter health and safety standards at Cintas laundry facilities.

[28] The company offers uniforms for rental and direct purchase, restroom and chemical supplies, mats, microfiber towels, mops, disinfectant sprays, and hand sanitizer.

The company also sells first aid supplies, personal protection equipment (PPE), AEDs, training and compliance courses, eyewash stations, and water coolers to businesses.
