Care & Maintenance
As the stone is in high demand and limited quantity, suppliers often treat the marble with great care to ensure the polished stone lasts for decades, and to preserve the fine details of the marble.

1. Avoid acidic solutions for your marble
Marble slabs are exceptionally sensitive to acidic solutions, as substances like vinegar, lemon juice, and boric acid which are used in cleaning solutions can all corrode the marble varnish, and lead to etching in the marble when the polished material comes in contact with acid.
Instead, clean slabs of marble with only stone-safe cleaners. There are plenty of commercial cleaning solutions that can be safely used on marble, and liquid castile soap mixed with water can also be used to bring the shine back to the slab.
2. Have professionals care for the marble
As Nero Portoro types of marble are exquisite and expensive, your best bet in caring for the marble is to get professional marble cleaners who have experience dealing with the material. Professional cleaners will be able to assess the condition of the marble, and clean or re-polish the slabs as they see fit to bring the shine back to the surface.

Still, nothing compares to the grace and style of black marble, and true Nero Portoro marble is noted by a signature, sleek, black stone contrasted with toned white and gold veining that no imitation can replicate.
