Grease & Oil - Slate

Removing Grease and Oil from Slate Surfaces

Oil and grease stains are a common problem on slate patios, garden paths, and outdoor dining areas. Whether from barbecues, garden equipment, or accidental spills, these stains can be stubborn and unsightly. Although slate is less porous than some natural stones, oil can still cling to its surface and settle into textured areas, making it difficult to remove with standard household cleaners. Without proper treatment, stains can become embedded and dull the slate’s natural finish over time.

How Do Oil and Grease Stains Occur on Slate?

Common sources of grease and oil stains include:

• Barbecue and Cooking Oils — Spills and splashes from outdoor cooking areas.
• Garden Equipment and Tools — Leaks from lubricants or oils used in maintenance.
• Household and DIY Spills — Solvents or oils from outdoor projects or repairs.

If untreated, oils can bind to the slate’s surface and settle into natural clefts or textures, making removal increasingly difficult and potentially causing permanent discoloration.

Why Is Oil and Grease Removal Challenging on Slate?

Oil and grease do not dissolve in water, so they resist regular cleaning methods. They adhere tightly to stone surfaces and penetrate crevices or textures, especially if the slate is unsealed or weathered. Because slate varies in density and finish, removing these stains requires specialist care to avoid surface damage.

Safe and Effective Oil Stain Removal for Slate

The best approach is to use a specialist degreaser formulated specifically for natural stone:

✔ Breaks down oil and grease molecules, lifting them out of textured areas.
✔ Cleans thoroughly without damaging or discolouring the slate.
✔ Safe for all slate finishes, preserving natural texture and colour.

Repeat Applications May Be Necessary

Due to slate’s texture, a single treatment might not fully remove stubborn or set-in stains. For best results:

• Apply the degreaser generously to affected areas.
• Allow time for the product to work and break down the oil.
• Rinse thoroughly with clean water.

Let the slate dry, then reassess and reapply if needed—waiting a few days between treatments.

This ensures deep cleaning rather than temporary fading.
