Pressure washers are reliable and make cleaning concrete surfaces fast and enjoyable. This simple guide will help you power wash your concrete patio without damaging it.

Step Three

Select a pressure washer; pressure washers come in electric and gas-powered models. You must choose the model and pressure that best suit your concrete patio needs. When using a pressure washer, you can choose between different nozzles; this nozzle will determine the flow rate of your mixture. When you’re ready to start cleaning, connect the pressure washer to a hose. Rotate the spigot valve clockwise to allow water flow, and hold the pressure washer trigger down.

Step Four

Test the pressure washer on a small area to ensure everything is good before proceeding. If your concrete patio is flat, you can start on any part, and if it’s sloped, position yourself in the center of the top part of your patio and start power washing. Repeat soaping and washing until the area is cleaned and all stains removed.

Step Five

Rinse away the detergent into your patio drain and allow your concrete to dry before you return any of your furniture.

Surface degradation and damage to the mortar are some effects that might result after pressure washing your driveway. Below are a few steps you can employ to clean a concrete driveway without pressure washing it.

Remove Debris

Most times, the cleaning solution our patios need is to clear and get rid of loose debris and dirt. This can be done by hand picking or sweeping the surface. Sweeping off the dirt and grime from your concrete patio will reduce build-up.

Clean with Commercial Cleaning Products

Commercial cleaning solutions come in different forms. Some are mild, harsh, or even harmful to patio surfaces, and you can use commercial cleaning products to wash out any stain after clearing the surface. When cleaning with commercial products, you will need some essential items to make the work easier. Vinegar, baking soda, bleach, or muriatic acids are mild commercial cleaning solutions you can employ when cleaning.

To create a cleaning solution with baking soda, dilute a half cup of baking soda with one gallon of water or one part with one vinegar to make a cleaning solution with water.  When there is a deep stain on your concrete patio, you can pour the cleaning solution into that area and wait for it to absorb for some minutes.

Pour your cleaning solution over your concrete patio and let it settle for ten minutes. Scrub hard into the concrete and brush off every stain from your patio. If the stain does not go off after using the vinegar solution, you can pour baking soda directly on it and allow it to sit in for not more than ten minutes, then scrub again.


The last stage is important; always rinse off every cleaning solution from your concrete patio. After rinsing, allow your patio to dry before you return your furniture.

How to Clean Dog Urine From Concrete Patio

Dog urine can stain your patio and leave behind an ugly stench. And sometimes, it never goes away no matter how hard you scrub with vinegar or bleach. When dog urine seeps into the concrete, getting rid of the smell can take a long time. Once you have noticed dog urine on your patio or perceive the smell, you should immediately clean it off. To get rid of dog urine, you must first:

  • Clear the area and remove any dirt or debris from the patio surface.
  • Use a garden hose to wash urine away from your patio surface. Make sure to keep pets away from the area when working.
  • Apply an odor eliminator to clear urine odor from the environment.
  • Apply a commercial cleaning product on the spot and allow it to sit for at least ten minutes before you scrub. It takes ten minutes for vinegar, baking soda, or bleach to penetrate through concrete. Apply more odor eliminators on the urine spot and scrub well.
  • Rinse your concrete patio and allow it to dry.

Cleaning your concrete patio properly after your dog urinates will remove the smell and leave the spot clean. However, if you don’t teach your pets to use the toilet or the spot you have made available for them, they will keep using your patio area. You can consider waterproofing your patio after eliminating the urine space. It is best to be on the lookout for your pet and guide them.
