Help with danish oil on stone paving

[Rmm]

While applying oil to my timber overhead door canopy I realised too late that the wind had moved the protective sheet exposing part of the stone slab entrance steps and I now have about six £2 coin sized oil spots on the stair treads.
I've tried scrubbing with soapy water and rinsing with boiling water and I've tried putting white spirit on the spots and then scrubbing with soapy water.
Neither appear to have made any difference. Is there anything else I can try or am I stuck with a spotty step?

I had some spots of danish oil on my kitchen floor, which I think I eventually shifted with isopropyl alcohol and a lot of scraping. You would expect white spirit to work but, if I recall correctly, it failed.

This was on ceramic tiles. If your stone is absorbent, you may be out of luck.

Yeah they are Indian stone slabs which have an absorbent surface but it may be worth trying the isopropyl alcohol.

Biological laundry liquid mixed with hot water. I measure of liquid to 2 measures of hot water and let it soak right in by covering with mixture-soaked rags.

Vegetable oil oxidises into varnish quite quickly. That's how oil paint works. A stronger solvent such as cellulose thinners might break it down, or a strong alkali. Old fashioned paint strippers used caustic Soda. AFAIK no paint stripper on the retail market is much good now.

I use linseed oil, and white spirit is ineffective once it has hardened.

I have previously used MC paint stripper to remove Danish oil from worktops, prior to sanding them. It only took seconds for it to lift 6 coats

I have not used them on stone though.

BTW MC is the old school paint stripper. You can still purchase it but there are minimum purchase quantity restrictions (5L+), designed to discourage DIY usage because of concerns about it being carcinogenic.

MC is methyl chloride.

I have found someone that sells it in significantly smaller quantities. PM me if you want a link.

methyl chloride.

Ah yes, I remember now.
