The car washes were held at the Bass Pro Shops in Rancho Cucamonga and at the Auto Club Speedway in Fontana. Proceeds from the sale of NASCAR pins at Stater Bros. Supermarkets also went toward the fund.
Participating stores across Southern California sold more than 3,500 pins.
"Loma Linda University Children's Hospital is tremendously grateful to Auto Club Speedway, The NASCAR Foundation and Stater Bros. Supermarkets for their recent efforts on behalf of Loma Linda University's Children's Hospital. It would not be possible for us to provide care for our children without the help of these outstanding community partners," said Zareh Sarrafian, an administrator at Loma Linda University Children's Hospital.
Since 2008, Auto Club Speedway has raised more than $150,000 for local charities during its NASCAR Day efforts.
