Cleaning removes surface dirt and soap residue but cannot fix etching, scratches, or deep stains that penetrate the marble. If your marble walls look dull, cloudy, or rough after cleaning, the damage goes deeper than what cleaning products can reach.
Restoration actually removes damaged marble surface and rebuilds the finish. We use diamond polishing equipment to eliminate etching, extract deep stains, and restore the original polish level. This process addresses the underlying damage rather than temporarily masking it.
Think of it this way: cleaning maintains marble between restorations, but restoration fixes accumulated damage that cleaning cannot touch. Once marble becomes etched or deeply stained, only professional restoration can return it to its original condition.
