Grease & Oil - Slate

Grease and oil stains on slate can be tough to tackle, as slate’s layered structure and occasional porosity make it sensitive to intense treatments. PureSeal’s grease and oil removers are carefully formulated to penetrate slate safely, breaking down stubborn residues from cooking oils, barbecue spills, and motor oils without risking delamination or damaging the stone. By letting the chemicals do the work, our products minimise the need for high-pressure applications, reducing the risk of slate layers separating.

For lighter stains, a single treatment may be effective, while deeper or older stains may require multiple applications to fully clear. Always follow the product instructions closely, use low-pressure application methods, and test a small area before full application to ensure compatibility with the slate. With PureSeal’s powerful yet slate-safe formulas, professionals can achieve a thorough clean, restoring the stone’s natural appearance while preserving its structural integrity.
