Sprinklers, reclaimed water and rust stains
Lawn irrigation here is a frequent cause of trouble. Sprinklers that spray walls, driveways and lanai screens can leave orange rust stains, especially where the water has iron in it. Reclaimed water, which many communities use for irrigation, can leave marks too.
Rust is a different problem from algae. It does not respond to the same solution, and some stains need a dedicated treatment. Adjusting spray heads after a cleaning keeps the stains from coming back. We look at where the water hits before choosing methods, and we point out heads that wet the wall or the paver edge, so the fix lasts longer.
