"Lighten stain on concrete by pressure washing it. Unfortunately, these older and more porous surfaces can also be damaged by the wrong tip or technique more quickly.

That is why aside from the regular nozzles used for pressure washers, it is best to use a Pressure Wash Surface Cleaner attachment from bestcargurus in cleaning flat surfaces such as brick and concrete.

A pressure washer surface attachment from bestcargurus gets cleaning jobs done up to 4X faster than the usual spray nozzles. The splash-free skirt keeps you dry while you clean and you won’t experience any streaking problems due to its ability to keep nozzles at a fixed height from the surface. "
