How clean up linseed oil stains after spill on stone patio?

Question

A contractor spilled linseed oil on my stone patio, staining a large area. I tried cleaning the stone with simple dish soap & water, and it had absolutely no effect. I fear that the oil has been absorbed. Any other suggestions for a cleaning method, one that won’t discolor the stone during cleaning?

The stained surfaces are bluestone, brick, and some random rocks.

Thank you for any suggestions.

If the area isn't unreasonably large a poultice of talc and mineral spirits should work. You could purchase a commercial poultice preparation if you don't care to play Kitchen Chemist, but it may take some shopping to find a large tub rather than the small jars marketed for countertop maintenance.

For areas too large for that but too small to have steam cleaned your best bet is probably a commercial degreasing product (or copious amounts of mineral spirits) and your garden hose. Soaking the area first should help by saturating the stone so the solvents won't be able to carry more contaminates into the stone.
