Lithofin OIL-EX

A dark ring of cooking oil spreads across your polished kitchen marble, turning an elegant surface into a blotchy eyesore. Standard cleaners only smear the stain deeper. Lithofin OIL-EX erases that mark by drawing the oil out of the stone-no sanding, no etching.

What OIL-EX Does

OIL-EX is a neutral pH 7 poultice cleaner for natural stone, terrazzo, concrete, and cotto. The solvent-charged paste penetrates up to 10 mm, liquefies trapped oils, and wicks them into an absorbent matrix that dries to a powder. One treatment removes up to 90 % of fresh stains; deep, months-old spots may need a second 24 h cycle.

When to Use

• Marble kitchen countertop with olive-oil shadow - apply neat (1:1) over a 15 cm circle.
• Granite BBQ bench splashed by sunflower oil - apply neat (1:1) to a 5 mm layer, cover with film.
• Sandstone patio plate holding a grease-laden grill - apply neat (1:1) across each drip mark.
• Concrete garage floor stained by motor oil - apply neat (1:1) over 20 cm diameter spots.
• Terracotta tile near a fryer with long-standing grease - apply neat (1:1) and repeat after 24 h if needed.

How to Apply

1. Stir the ready-to-use paste until homogeneous, then spread a 5 mm layer 2 cm beyond the stain edges.
2. Cover with household cling film to slow evaporation and leave undisturbed for 2-24 h.
3. Remove the film, allow the paste to dry fully, then sweep or vacuum off the powder residue.
4. Rinse once with Lithofin MN Wash & Clean diluted 1:200 to neutralise remaining solvent.

Coverage: 0.5-1 kg per stain, equal to 0.2-0.4 m². Drying time before sweeping: minimum 2 h on marble, up to 24 h on highly porous sandstone. Re-treat immediately if a shadow remains.

Surface Compatibility

The poultice suits porous stones such as marble, granite, limestone, and concrete. Its neutral chemistry avoids etching acid-sensitive Mohs 3 stones while the solvent action is strong enough to penetrate low-porosity Mohs 7 granite. Do not use on glazed ceramic or stainless steel where oil sits on the surface-simply wipe those materials.

Choosing the Right Product

For large-area dirt films use MN Power-Clean at 1:5. For daily wipe-downs select MN Wash & Clean at 1:200. After removing a stain, seal the stone with MN Stain-Stop to prevent repeat penetration.

Pro Tips

• Score the cling film with two pinholes; minimal airflow accelerates solvent evaporation without skinning.
• Warm the stone to 25 °C with a hair dryer before application-oil viscosity drops 30 %, improving extraction.
• On vertical surfaces secure the paste with painter’s tape to maintain a uniform 5 mm thickness and avoid sagging.
