Natural Stone Hearth Cleaner

Once cool, remove loose ash, spray a neutral stone cleaner, wait 2 to 3 minutes, wipe, and follow with clean water. Never use vinegar, lemon, or descaler; they etch marble.

Yes, on granite, slate, quartzite, marble, and limestone. Test honed or tumbled finishes first.

No. The neutral formula doesn’t react with stone and has no abrasives, so the polish stays.

Use a near-neutral cleaner with no acid, no strong alkali, and no abrasives. Marble and limestone are calcium carbonate, so vinegar, lemon, and descalers etch them, and harsh degreasers can dull a polished face over time. This formula (pH 7.0–8.5) loosens oily soot with surfactants and a mild solvent rather than reacting with the stone. Finish with a clean damp cloth.

Let the stone cool, vacuum or brush off loose soot, spray, wipe once the grime loosens, and finish with a clean damp cloth. Limestone is calcium carbonate and fairly porous, and acids etch it on contact, so skip vinegar, lemon juice, and descalers entirely. On honed or tumbled limestone, test a hidden spot first.

Repeat 2 or 3 times with 3 minutes of dwell each. For soot deep in the pores after years, a stone poultice works.

On sealed stone, reapplying sealer per its instructions helps keep future soot from soaking in and makes cleaning easier.

Glass creosote is tougher; use the Fireplace Glass Cleaner. This one is made for stone.

Vacuum or brush off loose soot first. Wiping it wet pushes loose soot into the stone’s texture and makes it darker. Then spray.

Everyday water marks, yes. Crusty mineral scale won’t dissolve in a neutral cleaner—use a descaler on granite, but never on marble or limestone.

Monthly during the burning season, while smoke film is thin. Dust with a dry cloth otherwise, and do a thorough clean at season’s end—then decide whether the stone needs resealing.

Wait until the stone is cool, and stick to the surround and hearth. Hot stone isn't a surface for this cleaner, and neither is the firebrick inside the firebox. Clean the outer stone between fires, ideally monthly during burning season.

Three things: whether to bundle with the fireplace glass cleaner as a winter kit, the size of your fireplace market (North America, Europe, Australia), and lemon or unscented. The core claim is “neutral, won’t etch marble”, so feature it on the label.

Free samples are usually ready in 3–5 days. Standard MOQ is 500 bottles, and bulk orders are scheduled after packaging and labels are approved.

All of it: formula direction, scent, fill size (500 mL spray, 1 L refill, and more), mist or foam trigger, label design and language, and ecommerce bundles with the Fireplace Glass Cleaner.

Yes, we ship samples first. Test them on polished marble and granite panels with soot like the ones your customers handle, and record soot removal, effect on polished marble gloss, and residue. That tells you more than a before-and-after photo.

We provide SDS/MSDS, a TDS, and batch COAs, plus bilingual label content for your target market. They aren’t posted publicly; we send them per project on inquiry.

Pricing is tiered by packaging, trigger or cap, label, and order quantity, starting at the 500-bottle MOQ. Send your target quantity, fill size, and packaging needs, and we’ll quote unit prices by volume tier with sample and lead-time details.
