Concrete is a durable and resilient material used commonly in driveways, sidewalks, patios and walkways. After being exposed to the elements, concrete can lose its brightness and clean appearance. You can restore brightness to concrete by using a few simple items.
Rent or borrow a power washer if you don't own one. Power washers are available for rent from many home improvement stores for an hourly rate.
Attach the power washer to a garden hose. Start the power washer. Turn on the water and use light pressure to moisten the entire surface of the concrete to be brightened.
Apply a cleaning agent to the surface of the concrete. Use a mix of one part liquid bleach to one part water or laundry detergent.
Use a long-handled scrubbing brush to thoroughly scrub the surface of the concrete. Make sure to scrub all corners and edges of the concrete well. Repeat scrubbing as necessary across every portion of the concrete.
Rinse away the cleaning agent using the power washer. Low pressure is usually sufficient for this process.
