HOW TO CLEAN A CONCRETE PATIO

Cleaning your patio without a pressure washer

General patio cleaning does not require special tools or equipment and can be done in just 3 easy steps:

  1. Rinse dirt/debris off the concrete surface with a garden hose.
  2. Apply a small amount of liquid dish soap and scrub with a push broom.
  3. Rinse well with a garden hose until there is no sign of soapsuds.

Tip: If you’re going to be resealing your patio, wait 24 hours after cleaning for it to air dry. If you’re in a hurry, a leaf blower can be used to speed up the drying process.

Removing fertilizer stains from a concrete patio

Fertilizer from your lawn or planters can leave stains on concrete. The ingredients in fertilizer penetrate and react with the cement, causing a permanent color change. Try using a clear white vinegar, diluted 50:50 with water to bring out the stains. Test in a small area first and be aware that the acid may etch or change the profile of the concrete in the areas you clean.

PATIO MAINTENANCE TIPS

  • Reseal every 2 or 3 years.
    Like waxing a car, resealing your concrete patio makes it as vibrant as the day it was installed. Learn more about sealing concrete patios.
  • Don’t let leaves or other debris linger.
    Remove anything that could cause stains immediately. Concrete is porous and can absorb dirt and debris.
  • Be careful with salt.
    Deicing salts or even rock salt from an ice cream maker can be harmful to the sealer on your patio.
  • Install a shade structure.
    Not only will you be more comfortable outside in the summer, but protection from direct UV rays will extend the life of decorative finishes and sealers.
  • Use saucers underneath potted plants.
    This will prevent water, soil and fertilizer from draining onto your concrete and leaving stains or growing mold.
  • Make sure downspouts don’t drain onto the patio.
    Direct runoff into your landscape where the water can soak into the ground. Or connect your downspouts to a patio drain system. More on Patio Drainage.
