Rust stains from a A/C overflow running down the side of a house, can be removed with Lime-a-way ($1.00 Bottle), most of the time.
Just spray on a brush and wipe over the high areas or spray directly on the low areas. The stains just start to disappear without scrubbing.
Don't forget to rinse out your brush.
