More than an eyesore
Bird droppings are acidic. Left on stonework, paint, metal or glass they etch and stain, and a heavy build-up of pigeon guano on a walkway is slippery and unpleasant to be near. Dried guano should not simply be dry-brushed into the air either, which is why it is wetted and treated as part of cleaning.
Bird droppings removal cleans the affected surface safely: droppings are moistened, loosened and washed away, with treatments for the staining that can remain on porous surfaces. On solar panels, droppings are removed with soft brushes and pure water so the glass is not marked.
This page covers cleaning only: we do not offer pest control, bird proofing or deterrent installation. For panels specifically, see solar panel cleaning, and for the rest of a commercial site, see commercial exterior cleaning and pressure washing.
