How to Clean Limestone Without Damaging It (Austin Guide)
From home exteriors to retaining walls, fireplaces, and entry columns, limestone is part of the Austin look. It is also one of the easiest surfaces to ruin with the wrong cleaning approach. Here is how to do it right.
Why limestone is tricky
Limestone is soft and reactive. Acidic cleaners eat into it and high pressure etches the surface, leaving it pitted and worse than before. Once limestone is etched, there is no easy fix. This is why limestone needs a specialist, not a general power washer.
The safe method
We use pH-neutral, stone-safe solutions and low pressure to lift mold, algae, and the gray organic film that dulls Austin limestone. The stone comes back bright and intact. Acorn, leaf, and pecan tannin stains, common across Travis County, respond well to the right treatment.
What to avoid
- Acidic or bleach-heavy cleaners that react with the stone.
- High-pressure tips that etch and pit the surface.
- Scrubbing with wire brushes that scratch.
