I’m in search of best practice to clean this metal siding, any advise is much appreciated!
Ironic, this evening I was requested to quote a similar building (though not this one). Mine is a horse arena, my plan was to recommend my normal house mix and procedure.
Hit it with your house wash and see what it does. If it’s still there, then heat it up. Trial and error or start searching. Either way post the outcome and the method behind it.
What do you want to bet he’s running 3/16" id tubing on it? lol
I’m not sure what your normal hw is but it should be fine
