How to Clean Concrete Equipment
- 1). Rinse concrete off all concrete equipment before it hardens, if possible. Use a scrub brush to clean as much concrete off equipment as you can.
- 2). Use a hammer and concrete chisel to remove chunks of dried concrete from equipment.
- 3). Saturate dried, stubborn areas with concrete dissolver. If this product dries before concrete has softened enough to remove, do not rinse. Apply more concrete dissolver to the area until the concrete has softened enough to be rinsed off the equipment. Dry all equipment thoroughly to prevent rust.
