Natural Stone Care Through a Utah Winter

Blog — February 20, 2026

Salt and de-icer are the real threat

Calcium chloride and rock salt tracked in on boots are acidic enough to etch unsealed marble and limestone within a season. A walk-off mat at every exterior entry, and a quick sweep before mopping, prevents most of the damage we see in older homes.

Reseal on a schedule, not when it looks bad

By the time water stops beading on a sealed stone floor, the sealer has already been failing for months. We recommend resealing natural stone entries and mudrooms annually, and other stone surfaces every 12–18 months, using a penetrating sealer rather than a topical coating.

Cleaning products matter more than people think

Standard grocery-store cleaners are often too acidic for stone. A pH-neutral stone cleaner is inexpensive and prevents the dulling that vinegar-based or citrus cleaners cause over time.

When honed beats polished

In entries and mudrooms specifically, we usually recommend a honed (matte) finish over polished — it hides the fine scratching from grit and salt far better, and it's less slippery when wet.
