How to Clean Concrete with a Pressure Washer
Choose Your Pressure Washer Settings
For more optimum cleaning of your concrete, your pressure washer must have a pressure rating of at least 3,000 PSI and at least 15.1 liters flow rate per minute for more efficient cleaning of the concrete.
This is the needed amount of pressure that is ideal for cleaning tougher dirt and debris that has piled up within the walls.
Select the best spraying option, which is high. Using a 40-inch spray tip is a good idea.
There are user-friendly models that offer superior quality, which is also why it is essential to choose the best electric pressure washer that will fit your cleaning purposes.
The next important thing you should do is to prepare the right amount of cleaning solution. You must have a bucket with detergent ready before proceeding to do further preparations.
Prep the Concrete Surface
In order for you to be successful in cleaning concrete, you must observe proper preparation. If you like to do the cleaning yourself, it will make it easier and faster for you to do the following task if you prepare the area beforehand.
You might need to temporarily move the deck furniture or planters if you happen to have any of those around the surface.
Consider removing obstacles that may be blocking the concrete. You want to cover plants or gardens to avoid contact with the cleaning chemicals and pressure of the washer; use tarps or plastic cloth for this.
Remember to also protect exposed outlets or electrical wires by covering them with any plastic or taping waterproof tape over them.
Trisodium Phosphate (TSP) is well known for its cleaning abilities. You can use TSP as a cleaning agent to help ease the process and remove oil and grease.
Look for the manufacturer’s instruction guide regarding the application of this product, and remember to follow the safety measurements.
Run a Spray Test On a Spot Before Cleaning
Before you start the actual cleaning process, you may want to get used to the washer’s power so that you know how to control the hose.
Depending on what you may need to do best, you may decrease or increase the level of power of the spray.
You can either adjust it at the nozzle or just change your distance from the concrete by holding the wand farther or stepping back.
Maintain a Steady Pace While Cleaning
Make sure to wash firmly and have a steady pace when you clean concrete. Always pass one section at a time, focus on cleaning the area thoroughly, free it from the dirt you are trying to remove before moving on to the next section, and don’t move the pressure washer hose around too much.
More importantly not too rapid to make sure that every section is cleaned evenly and there are no visible streaks once the area has dried because that will not look as pleasing, and you certainly wouldn’t want your concrete wall to look uneven.
