What Size Pressure Washer Do You Recommend?

What Size Pressure Washer Do You Recommend?

The ideal pressure washer for graffiti removal will spray approx. 2-3 gallons of water per minute at approx. 2000 – 3000 psi.

Typical graffiti can be removed easily with a small cold water machine such as our EcoBlaster. However, for the commercial contractor we always recommend moving up to a hot water unit (see Hot vs Cold). 

Even the highest PSI pressure washer won’t clean a dirty car, so it’scertainly not going to remove graffiti which has impregnated a poroussurface. Don’t ever think that it will remove graffiti by closeblasting. One can easily cause damage to walls by blasting too close orusing the wrong types of tips because the graffiti removers have eithernot been left on long enough, have dried out too soon, or have not beenflood coated adequately on porous brick and masonry surfaces.


Always remember that the pressure washer is the last thing started. Ingraffiti removal, the pressure washer is only being used as a quickrelease rinse of already dissolved or softened graffiti. It is thegraffiti removal products which should be doing most, if not all of thework.


Use a 15° (yellow) fan tip for graffiti removal and keep your gunstrokes even and gentle, watching carefully not to come in too close tothe surface. If you need to come in closer, be sure to keep the gunmoving on the surface to avoid knocking out old mortar joints on brickor removing cement stucco from the surface.
