I have not good results when working with aluminum siding. I have given an estimate on an aluminum siding home that has a medium build up of mildew. The siding is white aluminum, some dust and dirt. The home owner has presiously tried to remove the mildew himself before calling me. I use all cold water and I don't like acid's. Any and all suggestions would be appreciated. Thanks folks !!
