To clean brick there is not a definitive answer to this question because it depends on the condition of the brick and the specific situation. In general, power washing is more aggressive and can be more effective at removing dirt, grime, and other debris from the surface of the brick. However, power washing can also be more likely to damage or wear down the brick if it is used excessively or if the wrong type of nozzle is used. Soft washing is less aggressive than power washing and is therefore less likely to cause damage to the brick. However, it may not be as effective at removing deep-seated dirt, grime, and debris. Consulting with a professional is the best way to determine which method is appropriate for your property. We appreciate TS Services for providing this helpful information.
