Why this product
pH-neutral formula
Made for natural stone. It won't etch marble the way many all-purpose cleaners do.
Safe on polished stone
No abrasives or acids, and no film left behind to dull the shine.
What our crews use
Chosen over thousands of home and commercial jobs across Ontario.
In context
Made for the kinds of stone we restore every week across the GTA.

Daily cleaning for polished marble entry floors. It's what we recommend after we restore a lobby.

Dilute it as a mop soap for kitchens and honed tile. Dry-mop the grit first, then use a well-wrung microfibre mop.
Full description
Our everyday cleaner for stone floors, honed counters, showers, and grout.
MC 24 Daily Stone Cleaner is an acid-free soap that cleans and conditions natural stone. Use it for regular mopping of stone floors, and on honed counters, showers, and grout. R-311 is the spray for polished counters; MC 24 is for surfaces that take footsteps, mop water, and tracked-in grit every day.
It cuts grease, lifts light dirt, and breaks down the hazy film that builds up in grout when the wrong cleaner leaves residue, or when the joints never get cleaned. It has no acids or abrasives, so it won't etch marble or strip the sealer.
Always dilute it as the label says. The right strength keeps polished marble safe, stops soapy buildup in grout, and makes a bottle last for months. A stronger mix won't clean better; it usually leaves a slippery residue and wears out the sealer faster.
Used as directed, it's suitable for polished marble, limestone, travertine, terrazzo, slate, and ceramic tile floors. In condos and commercial lobbies it's used on floors that mix stone tile and grout, where one product has to be safe for both.
The 1 Litre bottle suits most homes. Property managers, cleaning contractors, and multi-unit buildings usually order the 5 Litre size: the same product at a lower cost per bucket.

How to use
MC 24 is diluted for mopping and wiping. It isn't a countertop spray. Mix it as the label says and dry-mop the grit first. Regular cleaning is the best protection against scratches and grout film.
Dilute it
Mix MC 24 with lukewarm water in a clean bucket at the ratio on the label. If staff mop for you, post the ratio for them. Change the water when it turns grey or smells stale, or you'll mop dirt back into the grout.
Dry mop first
Dry-mop the whole floor with microfibre, or vacuum with a hard-floor head, before any water goes down. Sand, salt, and tracked-in grit cause most of the fine scratches on polished marble and limestone.
Mop and scrub lightly
Use a well-wrung microfibre mop or soft cotton pad. Work in small sections toward the door so you don't walk on wet stone, and give extra attention to grout and tile edges, where film builds up. A light back-and-forth motion lifts soap residue; no scouring pads.
Tip: A damp mop is enough. Too much water streaks polished stone, slows drying, and pushes dirty water into the grout.
Rinse if the label says to
On polished marble and limestone, follow the label: rinse with clean water, or wipe again with fresh solution if the floor was very dirty. Dry busy entries with a towel or fan so no one walks on wet stone. Slow-drying floors in winter are more slippery and more likely to mark.
