Pressure washing a driveway can be an effective way to remove stubborn dirt, grime, and stains, but it doesn’t always require a dedicated surface cleaner. In this comprehensive guide, we’ll explore a step-by-step process to pressure wash your driveway without a surface cleaner, ensuring a thorough and efficient cleaning.
Prepare the Area
Before you begin the pressure washing process, it’s essential to prepare the driveway properly. Start by clearing the area of any debris, weeds, or grass growing between the slabs or through cracks. Use a broom or leaf blower to sweep the entire driveway, paying extra attention to the cracks where dirt tends to accumulate.
Pre-treat Stains
Addressing stubborn stains before pressure washing can significantly improve the overall cleaning results. For oil stains, sprinkle a generous amount of sawdust or cat litter over the affected area and let it sit for several hours. This will help absorb the oil, making it easier to remove. For tree sap or other sticky substances, use a scrub brush and apply a commercial hand cleaner containing pumice or acetone to the affected area. Let the solution sit for a few minutes before scrubbing the area.
Mix Cleaning Solution
To create an effective cleaning solution without a surface cleaner, you can use a mixture of washing soda and hot water or powdered dishwashing detergent. Sprinkle the washing soda or detergent over the driveway and then use a garden hose to apply hot water, creating a sudsy solution.
Scrub the Driveway
Using a standard deck brush or a pole brush with stiff nylon bristles, scrub the driveway in sections, dipping the brush into the cleaning solution as needed. Apply moderate pressure and work the solution into the surface, paying extra attention to heavily soiled areas.
Rinse the Driveway
Once you’ve thoroughly scrubbed the driveway, use a garden hose sprayer to rinse the area, starting from the top and working your way down. This will help prevent dirty water from flowing over the already cleaned sections, ensuring a more uniform and effective rinse.
Additional Tips
For smaller areas or regular maintenance, consider using a pump sprayer filled with a mold and mildew remover solution. This can be a convenient and targeted approach for spot cleaning.
For a more comprehensive and long-lasting cleaning process, use a backpack sprayer with a concentrated cleaner like Spray & Forget. This type of cleaner has a residual effect and can continue to work for up to 18-24 months, reducing the frequency of deep cleaning.
