Get matched with top concrete driveway pros in Polo, MO

Concrete does well with a number of cleaning agents, as it’s a durable material. Choose from acidic cleaners, alkaline cleaners, and pH-neutral cleaners, in addition to antibacterial solutions. Your best bet is to simply read the fine print with your preferred detergent and make sure it mentions concrete as a viable surface. 

It depends on the type of surface, but if you’re preparing to pressure wash a driveway, you’ll start by using a broom or leaf blower to get rid of dirt, leaves, and other debris. Then, move any nearby items (like outdoor furniture and potted plants) and cover in-ground plants with a tarp or plastic sheet. After that, you can apply degreaser spray or another pretreatment solution to any stains and scrub them with a stiff brush before pressure washing.

You can whiten concrete for unsealed and unfinished concrete with a solution or either muriatic acid or bleach and water—but never both. However, if your concrete does have a stain, finish, or polish, keep in mind that these hard chemicals could damage the topcoat. Your best bet otherwise is to power wash outdoor concrete slabs or clean indoor ones with a gentle cleaner such as laundry or dish detergent.

The ideal PSI (pounds per square inch) for a pressure washer depends on the surface you are cleaning. For general home use, a pressure washer with a range of 2,000 to 3,000 PSI is recommended and powerful enough for most residential projects.

The specific PSI you should use varies by task:

• High-Pressure Tasks (2,500-3,000 PSI): Tough materials like concrete, stone, masonry, and brick can handle higher pressures. This is suitable for removing stubborn stains from driveways or cleaning graffiti.

• Low-Pressure Tasks (around 600-1,300 PSI): Softer surfaces require a gentler touch to avoid damage. Use a low PSI setting for cleaning wood decks (especially softwoods like pine and cedar), vinyl siding, outdoor furniture, and stucco.

For best results, choose the right nozzle for your surface, such as a 15-degree nozzle for siding or a surface cleaner attachment for driveways. Using an extendable wand can also make the work easier and more ergonomic.
