Will running CLR through cooling system do any damage?

Running CLR (Calcium, Lime, and Rust remover) through a vehicle's cooling system can potentially cause damage. CLR is an acidic cleaner and may corrode metal components, rubber hoses, and gaskets if used improperly or left in the system for too long. It's essential to follow the manufacturer's instructions and thoroughly flush the system with water afterward to minimize any risks of damage. Always consider using products specifically designed for automotive cooling systems for safe maintenance.
