EMERGENCY (room)

Also posted this over at PWC, but looking for some suggestions on cleaning the metal paneling on this structure. Little nervous about high pressure, caulking between these metal siding panels is in bad shape. Black dirt come off on your hand; probably not mold. Any type of softwash? Something to brush on and rinse off? Thanks in advance.



Man lift and soft wash??? Have not done that combo myself though!!

I would just try to wfp it. If it comes off with a hand wipe that may work great.
