Drive-Thru Pressure Washing in San Antonio, Texas


For the concrete driveway, it’s essential to apply a degreaser on the surface before starting the pressure washing process. This is to get rid of any oil or grease, as those can negatively affect the result. Following the application of a degreaser, spray the driveway with detergent to help loosen any thick or stubborn filth. Then, use a pressure level of 2,500 to 3,000 PSI and a 25-degree nozzle tip to rinse it down. To finish, apply a sealer for a longer lifespan.


Some drive-thru windows are made of glass, which naturally experiences its fair share of dirt and oil as well. Before cleaning, see to it that the window is completely shut to prevent water from entering the premises. Then, apply a cleaning solution or multi-purpose soap on the area, scrubbing if necessary. Rinse it down with a recommended pressure level below 2,000 PSI and a 40- to 60- degree nozzle as glass is more delicate than other materials.


Other drive-thru windows are made of high-grade plastic as they’re typically cheaper and safer at the same time. To clean plastic windows, a dish or laundry detergent usually works fine. Scrub the solution onto the surface before using low-pressure water (below 2,000 PSI) fed through a 25- or 40-degree nozzle to rinse the mixture down.


For aluminum surfaces, apply a cleaning detergent on the material and use a brush to scrub the detergent gently onto the area. If mildew is spotted, a vinegar and bleach solution can kill and remove the growth. Rinse it down with a suggested 25-degree nozzle and a pressure level of 2,000 PSI.


Be careful not to use cleaning solutions designed for wood or vinyl on steel surfaces as those may have adverse effects. To clean steel, simply combine 6 gallons of water and 1/3 cup of laundry detergent, then apply the solution using a fan tip. It is then recommended to rinse the area thoroughly using a pressure level of 2,000 PSI and a 25-degree nozzle.


Before applying detergent to brick surfaces, make sure to wet the area first. This is to avoid damaging the brick as the material is very porous and can easily absorb moisture. Then, apply a detergent solution to the area and allow it to sit for 5 minutes. To finish, it is suggested to wash down the area using a 25-degree nozzle and a pressure level of 500 to 2,000 PSI. Using too high a pressure can destroy the mortar in between.


For tile surfaces, it’s important to use a low-pressure level at all times. Too high a pressure can destroy the caulked seams and grout, thereby knocking the tiles loose. It’s equally important to inspect the tiles first for any gaps or openings. When spotted, these gaps should be sealed before cleaning the surface as water can settle inside and damage the material. For porcelain and ceramic tiles, power washing is not recommended.
