Can I use Bathroom & Shower Cleaner on marble or natural stone?Updated 6 hours ago

Generally yes on sealed marble, granite, travertine, limestone, and engineered stone when used as directed. Bathroom & Shower Cleaner is mildly alkaline (pH ~8) and non-abrasive, which is much gentler than acidic cleaners (vinegar, lime removers, descalers) that actively etch calcium-based stone. Still, natural stone is porous, sealants break down over time, and different stones react differently. Spot test first every single time. Keep dwell time short (1 to 2 minutes max on stone). Rinse thoroughly and dry with a soft cloth.

✓ Generally safe on sealed stone

Sealed marble, granite, travertine, limestone, engineered quartz. Mildly alkaline (pH ~8). Non-abrasive. Gentler than acidic descalers or scouring cleaners. Spot test first, short dwell, rinse thoroughly.

Skip Bathroom & Shower Cleaner on unsealed or porous stone, old or worn sealants (typically 5+ years without re-sealing), honed or matte finishes where any residue is visible, and stone you're genuinely not sure about the history of. For heritage stone, expensive countertops, or bespoke installations, ask the stonemason or supplier for their approved care products. When in doubt, use a dedicated stone-safe cleaner or plain water on a microfibre, and save Bathroom & Shower Cleaner for surrounding tiles and fixtures.

⚠ Skip on these

Unsealed or porous stone. Old or worn sealants (5+ years without re-sealing). Honed or matte finishes where residue shows. Heritage or bespoke stone (check with the stonemason). Anything you're not confident about.

Pick an inconspicuous area (corner of a tile, under a basin lip, edge of a benchtop). Spray a small amount of Bathroom & Shower Cleaner, wait 60 seconds (no longer), rub gently with a soft microfibre, rinse with water, dry with a clean cloth. Check closely for dulling, discolouration, etching, or texture change. Check again after 24 hours, some reactions show up later. If the test patch still looks identical to the surrounding stone after a day, you're clear to use on the rest.

✓ Four-step spot test

Once you've spot-tested and confirmed it's safe: spray Bathroom & Shower Cleaner onto a soft microfibre, not directly onto the stone (reduces contact time and prevents pooling). Wipe gently. Rinse the surface with a clean damp cloth or water. Dry immediately with a soft dry cloth, don't let moisture sit on stone or pool in grout lines. For weekly maintenance on sealed stone shower walls, a quick spray and rinse is fine. For benchtops and honed finishes, always apply to the cloth rather than the surface.
