What makes a polished marble floor lose its shine?
A polished finish is a very smooth surface that reflects light evenly. Anything that roughens it, even slightly, scatters that light. The common causes are fine scratches from grit and shoes, etching from acids, general wear in walking paths and a film left by cleaners or residue.
What is the difference between a scratch and an etch mark?
A scratch is physical: something harder than the surface drags across it. An etch mark is chemical: an acid, such as lemon juice, wine, vinegar or an acidic cleaner, dissolves a little of the marble and leaves a dull spot, often lighter than the stone around it. Wiping the spill away does not undo an etch, because the surface itself has changed.
Can the wrong cleaner make marble dull?
Yes. Acidic cleaners, including many bathroom, kitchen and tile products and vinegar mixes, can etch marble. Abrasive powders and scrubbing pads can scratch it. Cleaners that leave residue can build up as a haze. A stone-safe, pH-neutral cleaner is the usual advice, and checking the label for use on marble is worth the time.
How can I slow dulling down?
- Use mats at entrances to catch grit, and dust-mop or vacuum regularly (without a hard beater bar)
- Wipe up spills, especially acidic ones, right away
- Use a cleaner made for natural stone, and avoid vinegar and acidic products
- Use felt pads under furniture and coasters or trays on counters
Can a dull marble floor be fixed?
Often it can. Light dullness may respond to a stone polish, while deeper scratches and etching generally have to be honed out and the shine rebuilt by polishing. How far it can go depends on the stone and how deep the damage is. The difference between the two finishes is explained in marble honing vs polishing. Sealing afterwards helps protect against stains, as covered in how often to seal marble.
When should I call a pro?
General advice only goes so far, because the right fix depends on the stone, how deep the damage goes and how the surface is used. If you are not sure what you are looking at, or the damage is more than light wear, a stone professional can look at it before anything is done that cannot be undone.
