Degreaser + Wood table = Pissy woman
Try sticking cat litter over the stain to see if it'll absorb some of the mucoff then maybe email the company to see if there's a way to flush it out of the wood cos id imagine it'll mess with any oils you put on
Fucking hell with all this malarky it's probably easier to just get a new woman and let the table chill the fuck out in all it's dappled, mucky ignominy.
My Dad says "use wire wool and meths to remove the old varnish. rubbing along the grain".
As its only pine, you could sand it back and paint it a nice Pastel colour. Coat of varnish or some kind of sealer and it'll look great and clean easily.
Personally if you have the space to do it I'd take it outside , powersand it all off and restain it
