Marble is a calcium-based stone that reacts negatively to acidic substances, making it prone to etching. It requires a high-quality penetrating sealer applied according to the supplier's instructions and routine cleaning with pH-neutral stone-safe soap. Slate is a metamorphic rock that can be porous and prone to clefting or flaking; it requires a penetrating sealer to protect against stains and water infiltration. Unlike marble, slate is generally more resistant to mild acids but still benefits from specialized stone cleaners. Avoid harsh chemicals, vinegar, or ammonia on either surface. Verify your specific stone's porosity with your installer to determine the ideal sealing frequency.

What are the specific maintenance requirements for marble versus slate flooring?
Marble and slate are porous natural stones requiring distinct maintenance. Marble is highly susceptible to acid etching and staining from acidic liquids, necessitating frequent sealing and pH-neutral cleaners. Slate, while more durable, requires regular sealing to prevent moisture absorption and flaking. Both stones should avoid abrasive scrubbers that damage the finish. Always follow the specific stone manufacturer's maintenance schedule and sealer recommendations.
