It’s feasible to clean and reuse bricksl. From a “green” standpoint, it’s better to recycle them than to send them to the landfill. Used bricks are good for building all kinds of things — they make handsome walkways, patios and planter boxes. If you’re a little more ambitious, a brick barbecue or fire pit is not out of the question. Your only limit is your imagination. Cleaning the brick is labor intensive, but it requires only minimal skill and perseverance. Be careful not to break too many bricks when deconstructing the wall. Stack the bricks in a pile so they’re accessible during the cleaning process.
