Liverpool eco-engine product maker Cataclean Global is reporting a surge in sales to the United States. Cataclean Global director Graham Fraser said the company is pleased to report an increase in North American sales of 300 percent in the last 12 months. Mr. Fraser said the sales had been driven across the United States, helped by a tough stance on emissions inspections in many states and a strong relationship with its US licensee, Ohio-based Accel Performance.
