Permastone siding questions

[wjs0311]

I received a message asking if we can clean permastone siding, the thing is I don't really know much about permastone. Would DSing my regular house wash mix work or is there a special chemical/process that I should use? I used the search function and google with little to no results.
Thanks

Ok he sent me another picture. I spoke with Doug and I am going to just DS my usual house wash mix on it.

I have done some houses that the stone or simulated stone looks similar to that, house wash mix worked good.
