    Metal Building Cleaning - need advice

    This is kind of a basic question, but surprisingly, I've never cleaned a metal sided warehouse/building before. I need to give a bid on one tomorrow. My first thought is to just use a regualar house/exterior wash mixture, but I'm unsure of how it may effect the metal exteriors. The paint is in very good condition, and still very glossy and shiney. What I'm afraid of is the chemical causing the paint to fade, oxidize, or loss it's shine. I would actually be a little less concerned if the surface was already a bit dull or faded, but it's in really good shape, just mildewed and dirty. Anyone that has advice/experience cleaning metal building exteriors, I would love any info you could offer.

    Ive done them that were part metal and part dryvit. The dryvit had mold on it and i just used a 35/65 house wash and x-jetted. I didnt see any adverse effects on the metal and it still retained its shine. I didnt let it dwell on the metal areas for to long since it wasnt that dirty. If it was me i would start off with a mild house mix and strengthen it as needed.

    Just did a 500x100 metal building last weekend. Mold and mildew all over on the north side and the rest was just a bit dirty. I used 6% bleach and simple cherry. Downstreamed most of it and it came out perfect and pretty shiny. There were a few spots on the north side that were terrible and I had to xjet the mix on and give a little more dwell time but it came out excellent also. "It was only about 40 degrees here that day" I think you should be fine using your hw mix with real light pressure and it should clean right up.

    House wash mix with a little more soap than usual.I have done quite a few and they all clean up just like a house if they are mildewed.
