How Do You Clean and Care for Scagliola?

The honest answer up front: scagliola needs almost no maintenance if it is treated gently — dust it, keep it away from sustained water, and never reach for anything abrasive or acidic. It is polished gypsum, not stone, and that single fact decides every rule below: gypsum has no resistance to standing water the way real marble does, and its polished lustre is a surface sheen that harsh cleaning dulls rather than restores. Treated like the refined, decorative finish it is — not like a hard-wearing floor or a kitchen splashback — a well-made scagliola panel keeps its glassy depth for decades.

Why the rules are different from stone

Scagliola is pigmented gypsum plaster, worked by hand to mimic marble veining and then polished to a deep shine — the craft is centuries old precisely because it fools the eye that well. But the material underneath the illusion is gypsum, not calcium-carbonate stone, and gypsum’s one real weakness is water: it softens and can dissolve with sustained wetting, in a way true marble simply does not. That is not a flaw in the workmanship — it is the nature of the material, and it is exactly why scagliola belongs on feature walls, columns, fireplace surrounds and formal reception panels, and not anywhere near a shower, a sink splashback or an exterior wall. The same gypsum-hates-water rule governs stucco lustro, scagliola’s close cousin in the gypsum family.

The everyday routine

Dust, don’t wipe. A soft, dry microfibre cloth or a feather duster is genuinely all a scagliola surface needs day to day. Dust simply sits on the polished sheen; it does not bond to it, so there is rarely a reason to introduce moisture at all.

If it needs more than dusting, go barely damp — and dry it immediately. A cloth that is damp rather than wet, wrung out fully, followed straight away by a dry cloth to lift any residual moisture, is the ceiling of what scagliola should ever see. Standing water, a soaked sponge, or a “leave it to air dry” approach are the three fastest ways to dull or mark the surface.

Never scrub, and never use anything abrasive. No scouring pads, no gritty cleaners, no vigorous circular rubbing. The polish is a surface phenomenon — burnished into the very top of the gypsum during finishing — and any abrasive action removes exactly the layer that makes scagliola look like marble in the first place. Once that sheen is scuffed, it does not come back with more cleaning; it needs a professional repolish.

Skip the household chemical cabinet entirely. No vinegar, no bathroom or kitchen sprays, no alcohol-based glass cleaners, nothing acidic. Acids etch polished gypsum the way they etch polished marble — the surface loses its glassy clarity and turns matte or blotchy wherever it was touched, and this damage does not wipe away.

What to do about marks and knocks

A light dust film or a fingerprint smudge is normal and comes off with the barely-damp routine above. A genuine scratch, chip, or a dulled patch from an old cleaning mistake is a job for whoever installed it, not a DIY fix — scagliola repair means reworking pigmented gypsum and repolishing it invisibly into the surrounding surface, a skilled hand’s job in the same way the original finish was. Because scagliola is applied and polished by hand in the first place, a good repair genuinely disappears; a scuff sanded at by an amateur usually does not.

Where it should never live

Bathrooms with direct spray, kitchen backsplashes behind a working sink, pool surrounds, and any exterior wall are all the wrong home for scagliola — not because the look wouldn’t suit them, but because sustained water in those settings will eventually soften or stain the gypsum underneath the polish. If the brief is a marble look in a wet or hard-wear space, our marmorino or genuine stone routes are the honest alternative; scagliola’s place is the formal, dry, admired-rather-than-touched wall — a fireplace surround, a column, a reception feature — where its illusion gets to do its work undisturbed.

The verdict

Scagliola asks for very little: dust regularly, keep water away, and never reach for anything abrasive or acidic. Follow those three rules and a scagliola panel holds its marble-deep shine for a very long time; ignore any one of them and the damage shows up exactly where the polish lived.
