leaf stain concrete cleaning in Columbus
In Columbus, this comes up on historic-district houses, mid-rise buildings, hotels, and industrial sites. Uptown brick holds a green film. Industrial eaves go black. Drives in the older blocks are stained through. Oaks drop tannins into gutters and onto pale concrete. The print looks like a shadow of the leaf because it is.
Venues, churches, and high gutters stay on the calendar when house washing slows.
Tannins are the brown compounds in leaves and bark. Wet leaves sitting on concrete, a fence, or a deck print that brown into the surface. It is organic, so a soft wash often lightens it, and on a sealed, sound surface it may lift cleanly. On raw, open wood or old concrete it can hang on.
The prevention is boring: blow the leaves off before they sit wet for a week. We are not a weekly lawn crew. We can clean the stain that already happened. We will not pretend a wash replaces blowing the deck.
Do not confuse a tannin print with rust. Leaf prints follow the shape of a leaf. Rust follows a sprinkler or a piece of metal. The chemistry is different, and we do not spend your rust treatment on a leaf.
The full explanation, without the town attached, is the tannins from leaves and oaks article. The town does not change the chemistry. It changes the houses, the shade, and the clay.
