How can I get a rust stain (probably) out of an embroidered table-cloth?

[AMumInScotland]

I've got an embroidered & appliqued tablecloth, the body is white cotton or possibly a cotton/linen mix. And while it's been tucked away in a drawer, all folded up, it's managed to get a reddish brown stain along one folded edge. I'm assuming it's a rust stain from a screw in the back of the drawer.

The mark is luckily just on a white part, but I don't want to start soaking or dabbing at it randomly.

Any suggestions what I should try?

TIA

Hope this helps

Ooh, thank you, I'll add a lemon to my shopping list and give that a try

If it doesn't work, I googled rust removing from tablecloth and lots came up to try.

Thanks again!
