Stains like grease, dirt, grime, mold and mildew on concrete can stick out like a sore thumb and always seem to appear on concrete surfaces like walkways and driveways. Hosing them off to only find them coming back. Scrubbing often won’t completely remove them either. Mold and mildew will appear on areas that are moist and shady along with areas that don’t receive a lot of sun or heat. Concrete is porous and has lots of nooks and crannies that make mold growth very easy. When the weather gets warmer, it will make it even easier for the mold to grow. Cement is porous which makes these stains difficult to remove.
Power Washing Concrete Without Bleach
Bleach isn’t effective on porous surfaces and it doesn’t remove the spores that you can’t see. Pressure washing without bleach will be very effective in removing stains and it won’t kill nearby vegetation. Plus bleach can weaken concrete because it’s caustic. Pressure washers don’t use bleach. DO NOT put bleach in a pressure washer – it will ruin it. You can purchase a detergent that is formulated for mold and mildew removal and is safe for siding and concrete. Fill the tank on the pressure washer and apply the detergent and let it soak in. If areas start to dry, make sure you apply more soapy water. Once the detergent has had a chance to penetrate, the dirt and oils will begin to loosen from the concrete and you can start blasting the mold and mildew away. Use a powerful tip and hold the pressure washer about 10-12 inches from the surface. It shouldn’t take too long for the mold to start breaking up and you’ll be left with sparkling concrete. To prevent streaking, make sure you use smooth, overlapping strokes. Divide the area into sections to ensure you get the right method down and that the soap is washed away completely before you move on to the next. If you miss areas, you’ll be left with noticeable spots. Take your time and don’t rush. Heavily soiled areas will need extra sweeping motions. You can even slow down over these areas to let the pressure washer do its job. You can then seal the concrete with a good-quality acrylic sealer formulated for exterior use. Make sure the concrete dries for 2 to 3 days without any rain and in sunny conditions before sealing it.
