Brick cleaning???

[power Showers]

1st time cleaning brick w/ mortar w/ concrete slab entry ways. It's a school hose built in 1918 with an addition added in the 50's. located in New hampshire. The brick under the windows looks like there is "white" run off from the paint used on the trim. staining off the roof lines and some blackening area's.

Need to remove rust from concrete slabs.

I have a 4500psi cold water pressure washer. Can I remove the stains
