HOW TO CLEAN A DRIVEWAY
You may not pay any attention to how your driveway looks daily, but a well-maintained driveway provides a great first impression of your home. Despite its tough exterior, unsealed concrete is porous and easily absorbs liquids, which can lead to tough stains. The texture of the surface also provides plenty of crevices for dirt, moss, and other materials to accumulate.
Oil spills, ground-in leaves and dirt and everyday wear-and-tear make checking this home improvement task off your list seem overwhelming at first.
To clean a spotted and soiled concrete driveway, you'll need something that will also sink in and lift offending spots. Covering the stains with cat litter, sawdust, baking soda, and other absorbent materials can take care of fresh surface spills, but do very little to absorb what sinks below the surface.
Trisodium phosphate (TSP) is widely used to clean oil off driveways. It is strongly alkaline, so it will not harm your concrete, but it could cause skin irritation and even burns. TSP is also very bad for the environment. If it ends up in lakes and streams, the phosphates trigger an overgrowth of algae that results in a depletion of oxygen levels in the water, which can endanger fish and other aquatic life.
To maintain the lighter color of a concrete driveway, many homeowners turn to cleaning with bleach, but you should not power wash with bleach because it can damage your pressure washer.
Simple Green Oxy Solve Concrete and Driveway Cleaner can be used with a power washer or for manual cleaning of concrete surfaces including driveways, sidewalks, patios, and walkways. It improves the look of oil stains and removes grease, grime, and other discolorations while still being non-corrosive and non-degrading. Its biodegradable formula is safe for lawns and pressure washing equipment alike.
Simple Green Oxy Solve is an EPA Safer Choice Direct Release product, meaning its ingredients are specifically identified by the U.S. EPA Safer Choice Program to have ultra-low aquatic toxicity values, and are safer for contact with aquatic life or other sensitive environments. Therefore, it is a safer outdoor cleaner than most.
Regular cleaning of at least once a year can help maintain your home's curb appeal.
Before cleaning, hose down your driveway and allow it to dry. Also wet all nearby plants, shrubs, and grass with water. If your concrete is stamped or colored and you're going to be using a pressure washer, test for surface compatibility in an inconspicuous area with and without the cleaner.
