Cause 1: Etching from mild acids
Marble's calcite is vulnerable to mild acids found in everyday life.
Dull rings near sinks and kitchens are often etching, not dirt.
Cause 2: Soap and cleaner film
Excessive cleaner concentration can leave film and streaks.
That "haze" you see may be product residue.
Cause 3: Abrasion and micro-scratching
Grit, sand, and even some scrub pads can create fine scratches that scatter light.
Cause 4: Mineral deposits from hard water
Las Vegas water hardness is reported around 291 ppm (17 gpg).
Evaporation leaves minerals behind, creating cloudy buildup, especially near faucets.
Cause 5: A finish mismatch from spot repairs
If one area was polished or honed differently, the surface will reflect light unevenly.
The fix depends on the cause
- Etching or wear: refinishing (honing/polishing) to restore a consistent finish
- Residue: neutral cleaning, thorough rinse, dry
- Mineral buildup: careful removal methods that do not attack the stone (avoid acids on marble)
