Removing water marks on wood floor

[linspins]

Hi all,
We had engineered oak boards fitted all over our downstairs a few years ago. One patch, by the bifold doors, has become dryer and more pourous, probably because of the sunlight (even though it had protective uv oil on it). Now, when ever a kid or cat drops water on it, it marks and stains, and any food coming in to contact with the floor leaves grease marks.
I emailed the floor company, who sent back a woolly email recommending various treatments, which involved recoating floor by a special buffing machine and leaving to dry/cure for 8 days without use. They also said do entire floor in one go.
We can't do this, as it would be too expensive and whole floor doesn't actually need treating, only sun bleached bit. Also can't have the floor out of action for that long.
Can anyone recommend an easier way to remove water marks, food stains and then re oil and restore that patch of boards?
We oil our kitchen surfaces with danish oil and that 'sets' in 24 hrs which would be manageable for floor. Help!

Anyone?

How deep do the stains go? Are they only on the surface? Could you give the area a very light sanding, just to remove the stains then treat with Danish oil? Or, I've heard of placing a cloth soaked in hydrogen peroxide over the stain for several hours which lifts the stain but I've never tried it myself.

are you sure it was oiled, not lacquered?

Try mayonnaise....trust me it works to remove water stains from furniture.

(plus usual disclaimer about doing a discreet test patch first!)

you can bleach out stains from wood using Oxalic acid. You can darken and colour wood with Colron or similar spirit based wood dyes.

You need to sand off any finish first, so the product can reach the wood.

White spirit will remove fresh oil or grease, but not once it oxidised to gum.

Liberon has quite a good range of products at boutique prices.
