Bird droppings run pH 3 to 4.5 and carry grit, so they soften clear coat and abrade it at the same time. On a Lubbock summer afternoon one can etch measurably in under two hours. Lay a quick-detailer-soaked microfiber over it for a minute and lift: never wipe dry. Light etching polishes out from $250; deep etching through the clear needs repainting.
Bird droppings are acidic — typically pH 3 to 4.5 — and they contain grit from the bird's gizzard. The acid softens clear coat while the grit works as a mild abrasive. What is left behind is a crater or ring that stays visible after the dropping is gone.
Heat accelerates the reaction. On a Lubbock summer afternoon, a dropping can etch measurably in under two hours. Paint expands in heat, opening the surface, and the acid concentrates as moisture evaporates.
Light etching polishes out. Deep etching that has gone through the clear coat cannot be polished — it requires repainting. The difference is usually a matter of how many hours it sat.
Removal is part of any wash or detail. Etching correction starts at $250 for an enhancement pass and $350 for single-step.
In Lubbock summer heat, etching can begin in under two hours. The droppings are acidic (pH 3-4.5) and heat accelerates the reaction while paint is expanded and more porous.
Light to moderate etching is removed by machine polishing. If the etching has gone through the clear coat to the base color, polishing cannot fix it and the panel needs repainting.
Wash the spot and look at it from an angle in direct sunlight. Residue disappears. Etching leaves a dull ring, a visible crater outline, or a matte patch that stays after cleaning.
Do not wipe it dry — the grit will scratch. Soak a microfiber with quick detailer, lay it on the spot for a minute to soften, then lift it away without rubbing.
Within hours in summer. On a Lubbock afternoon the acid concentrates as moisture evaporates and can etch measurably in under two hours. In cooler months you have more slack, but same-day is still the rule.
Soak a microfiber in quick detailer, lay it over the spot for about a minute, then lift straight up without dragging. The grit in droppings is abrasive, so wiping a dry dropping is how it becomes a scratch as well as an etch.
It buys meaningful time rather than immunity. The acid works on the coating first instead of going straight into clear coat, so a dropping caught within a day usually leaves nothing behind on a coated panel.
