My wife has just applied a nice thick coating of external cornis oil to an oak oiled sideboard. It has darkened it somewhat. I have wiped as much as I can now but need advice as to how to rectify. Can I use sand paper to try and remove and if so, which grade would be enough? I wanted to apply danish oil to it afterwards. Any advice greatfully received.

Not a direct answer, but be advised that danish oil is actually a mix of BLO and varnish, not a pure oil.
Sounds like you're in the UK. I have no experience with cornis oil, but it might not be as bad as you're thinking. Any added oil will darken a piece a little.
Is this a new piece or an old piece you're trying to freshen up?
If you sand, start with 320 or 220. You want to use as fine of a sandpaper as you can get away with. The lower the grit, the more aggressive. You might need to get aggressive but start fine.
Thanks for the advice. It’s a new peice of furniture
If it is white oak you can probably start as soon as it feels dry. If it is red oak I would wait a while to see if any bleeds back out. Put some of the cornis oil on a piece of glass to gauge the cure time. Good luck!
Does anyone know exactly what "cornis oil" is? I'd never heard of it. A quick search makes me think the name is just a trademark of one UK manufacturer. From their claims, which include "allowing the wood to breathe," I'd guess a little bit of linseed oil and a lot of snake oil.
Hi, it’s an oil I bought to treat my garden furniture made by Alexander rose. I’ve no idea what’s in it.
John C2, I'll bet you're right. One reviewer on Amazon UK said it smelled like linseed oil to him but was darker. He guessed they added brown coloring to it.
It's been my experience that linseed oil soaks in pretty deep so trying to sand it away would be difficult.
I would be inclined to accept the color as-is and let it dry completely - 3 or 4 weeks - then lightly sand and top coat with varnish or danish oil.

Great advice thanks
What type of finish was originally on it? If it is new I would assume some type of finish was applied before you bought it. The oil may have not penetrated as deeply as you think. I would not sand it unless you want to completely refinish it. Get a bucket with water and a scrub brush. Add some dish soap to the water and give it a scrub wiping away excess with a dry towel. Once dry use some alcohol and a scrub brush working into grain and drying out excess oil. Wipe down with turpentine after. Rub with a scotch brite pad or similar to knock down grain and apply some orange oil followed by a paste wax. Should be fine then.
Funny, considering where we are having this discussion I was assuming he made it... but I if he did his wife would probably know better.
My thoughts exactly. Don’t think the wife would do that to something he just made.
So Callie I just potentially put danish oil over it without sanding
