CrystalSure Deep Clean Gel lifts years of stains and seals stone shine in minutes, delivering a two-in-one clean-and-protect result in a single pass.
If you see a coffee ring on granite, water marks on marble, or grout that darkens, the thick gel clings to the surface, penetrates pores, and draws out embedded grime while leaving a clear protective layer that makes future spills bead instead of soaking in. No scrubbing, no strong fumes, and no etching on polished stone.
Safe on polished marble and acid-sensitive stone; the formula is non-corrosive and pH-neutral, so it cleans without dulling the finish or removing seals. It tackles deep-set stains that surface cleaners miss and deposits a protective coating so stains stay from sinking back in. The gel's thickness helps it cling to walls, shower tiles, and backsplashes without dripping.
Bring your stone back in three steps: Step 1 — squeeze CrystalSure Deep Clean Gel directly onto the stained or dull area. Step 2 — brush in gentle circles to let the gel penetrate pores and lift trapped grime. Step 3 — rinse with clean water and wipe dry; the stone returns to a glossy finish with a clear protective layer that beads water off.

Suitable for marble, granite, quartz, slate, travertine, limestone, soapstone, terrazzo, concrete, ceramic and floor tile, grout. Capacity: 3.4 fl oz (100 ml).

Will this dull or etch my polished marble? No. CrystalSure Deep Clean Gel is non-corrosive and pH-neutral on stone surfaces.
Does the protective coating really last, or do you have to reapply every week? The protective layer holds through normal cleaning and daily use. On high-traffic surfaces like kitchen counters and shower floors, reapply every few months. On walls, backsplashes, and decor stone, much less often.
Can I use it on shower walls and vertical tile? Yes. The gel is thick enough to cling to vertical surfaces without dripping, so you can treat shower walls, backsplashes, and tile borders the same way you treat the floor.
Is it safe with kids and pets around? Yes. Non-toxic, non-corrosive, no bleach fumes. Rinse the surface and let it dry before letting pets or toddlers crawl across it.
Will it work on old grout, concrete, or terrazzo too? Yes. It works across the full stone family — including grout, concrete, terrazzo, and porous tile — wherever you've got dullness or stains sitting in the pores.
Try It on Your Worst Stain — Risk-Free Pick the stain that's been bothering you the longest — the coffee ring, the water spots, the grout line that won't lighten. Try CrystalSure Deep Clean Gel on it. If the stone doesn't come back, we'll refund you.
“Honestly thought the before/afters had to be fake. My granite island had a coffee ring I'd been hiding under a cutting board for a year. Spread the gel on, came back in 15 minutes, wiped it — gone. Now I'm using it on the shower marble.”
“I was scared to put anything strong on polished marble after I etched it once with the wrong cleaner. This didn't dull it at all. The water actually beads on the bathroom floor now.”
