Any fix for this limestone?

[Spare Tool]

Builder on the job I'm on has blobbed these limestone on two window cills, not sure what adhesive was used but he was using grey rapidest on a bathroom so presume it would be that.. They were fitted six months ago and never been sealed, they have no tiles left so any ideas to sort besides rippling em out?
Its not really my problem but said I'd ask for her..

I doubt after 6 months you'll be able to remove the adhesive stains.

If this is a case of give it a go or rip them out, the alternative is to stain the entire stone with linseed oil or similar. It may disguise the stains.

It's probably worth a shot before taking a hammer to them.

tell him it'll be cheaper to buy two new ones then have me come up to rectify them

Thanks Alan, sounds worth a go.. When you say or similar, anything specific?
Builders long gone Julian and won't be coming back, just thought I'd ask and see if there were any suggestions

linseed oil can be bought at most hardware shops Andy. You can dilute it down with some white sports so it's not so thick and penetrates easier. adding extra coats should darken it up.

Any inert oil would probably do. Linseed oil was the first thing that sprang to mind.

Sunflower oil, vegetable oil maybe? Just not after you've fried a pan of chips with it though.

Olive oil? That's a healthy alternative.
