Example of Pressure Wash on Moderate Flash Rust

Example of Pressure Wash on MFR:
Below: the substrate is dry- but it is darker (overall) than the original substrate.
This surface is dry within 5 minutes. The standard pictures in VIS-4 do not provide these types of illustrations of pressure-washed surfaces. The upper half is not washed; the lower half has been pressure washed.
Brush test on the Pressure Washed Surface.
Brush Test before Pressure Wash.
After Pressure Wash- there is very little faint color on cloth
After pressure washing the substrate, there is a faint marking at the upper edge of the cloth where the brush bristles contacted the surface.
The area has been mitigated from moderate to light flash rust.
