rusted engine blocks

In an open area, with plenty of ventilation, and away from everything else, you can use muriatic acid, commonly found at hardware stores, known as "brick acid" to remove the rust. Apply with a paint brush, wearing gloves and goggles. It WILL eat clothes and shoes.The vapors are hazardous, wear a mask, and they will rust exposed ferrous material. You must immediately flush the parts with water, and you must dry them and use something to prevent them from rusting again. It will even clean the water jackets.
