Advice please - removing water stain from wooden floor

[David_C (David Cushing)]

A good friend is about to move out of a flat, and she’s worried that the landlord is going to charge her for some water stains on the wooden floor. The stains are from water condensing on her water bottle, and running down when she put it on the floor next to the bed.
I can’t tell whether the floor is oiled/waxed or varnished.
Can anyone offer any tips on how to get rid of these stains?
(Just to pre-empt an entirely reasonable / logical question: I don’t think she’s willing to open a conversation with the landlord to find out what kind of flooring it is, as they don’t have the best of relationships - hence her moving out!).
Cheers

I’ve used ring remover on furniture tops and worked well…different brands…The liberion blurb is…

Follow instructions . Try a test area. Sometimes it dissappears. Sometimes it suppresses it and you might see a bit left behind.

Some very fine sanding 240 or 400 grit and leave the sawdust to full the grain. Actively try to sweep the sawdust to film over what’s left of the stain. Trick is don’t over sand…from a distance you want it to look natural wear and tear…rather than a sanded patch sticking out
