Deep Cleaning, done the right way.
Deep cleaning is machine-driven — a rotary or orbital scrubber with the correct chemistry lifts years of ground-in grime, detergent film, grease and biological growth that mopping only spreads around. It also cleans the grout lines, which is where most of the visible dirt on a tiled floor actually lives.
Sandstone's open pore structure is the whole point — it grips underfoot and looks natural — but it means aggressive cleaning erodes the surface and film-forming sealers peel. Everything is done gently: low pressure, neutral or mild chemistry, breathable sealers.
On sandstone: Sandstone is cleaned at low pressure with mild chemistry — aggressive washing erodes the soft, open surface.
The process
How sandstone deep cleaning works.
Step 01
Assess & pre-treat
We identify the surface and soiling, then pre-spray the right alkaline degreaser or biocide and let it dwell.
Step 02
Machine scrub
A weighted rotary machine with the correct pad or brush works the surface and grout lines; a grout brush gets the joints.
Step 03
Extract & rinse
The dirty solution is vacuumed up, not left to dry back into the floor, and the surface is neutral-rinsed.
Step 04
Protect
Grout is optionally sealed; sandstone gets a breathable impregnator; the surface is left dry and streak-free.

Frequently asked questions
Common questions, answered.
Why does my floor look dull even though I mop it often?
Usually it is a film of dried detergent plus hard water and fine grime. Mopping adds more of it. A machine scrub with an alkaline stripper removes the film and the shine returns.
My sandstone has black algae, lichen and green biological growth in shaded / damp areas — can deep cleaning fix that?
Yes — that is exactly what deep cleaning addresses on sandstone. We confirm the cause on the free site visit and quote the fix in writing. Book a deep clean for an overall haze that will not mop away, dark grimy grout, greasy kitchen and dining floors, biological growth on outdoor stone, or before sealing any floor.
How do I keep my sandstone looking good afterwards?
The essentials: sweep and rinse; only mild pH-neutral cleaner for washing; keep gutters and drainage clear so the stone is not permanently wet. We leave you a written care plan for the specific finish.
