Best Way = Professionally Cleaned
The best way to clean a concrete driveway or polished concrete surface is to hire an exterior cleaning service that will determine what type of materials are causing you surfaces to be “dirty”. This does make a difference. Depending on the material, the cleaning method could be completely different. First, the cleaning professional will remove all of the larger debris from the driveway. This includes leaves, rocks, branches, and small children that have wondered off. Second, they will apply a soft wash mixture to remove the baked-on grime. This mixture is your basic laundry detergent at different combinations. It includes primarily water with a little bleach and surfactant (laundry detergent) as the cleaning agents. They will allow this to sit and do its magic. The bleach will kill the bacterial and mold growths while the detergent will lift the grease and grime from the surface. Once this has set, they will pick a power washing pressure value that matches the age and integrity of the concrete to rinse the soap and dirt off the surface. The pressure matters because if it is too much it will etch away at the top layer of the concrete. This is not good.
Can’t I do It?
You can do anything you want as long as you accept the consequences of your actions. If you use the wrong mixture of ingredients you could kill your plants or not clean your concrete. If you use too much pressure in the wash you could etch away the top layer of your driveway. If you don’t do anything your concrete surface will slowly collect grease, grime, mold, mildew, and algae that will take over all of the edges and potentially spread to the siding of your home, if it isn’t there already. So, if you want it done right the first time, hire a professional today.
