Remove water marks from interior varnish

[spring]

condensation in the cabin has dripped on to the nav and saloon table and dried leaving round lighter varnish water marks, I don't know what type of varnish was used, the boat is 20 years old. I would have thought if it were polyurethane the water would not have left markers

how best to remove please?

Please do NOT try this on the strength of my post...

...but if you pour a small amount of meths on to the stain then put a match to it, all your troubles will vanish!

(...assuming you're insured)!

Apparently, the white stain is water moisture trapped under the varnish and unable to escape. The meths flame somehow draws it out. I've seen it done wih rings on coffee tables with quite remarkable results! Probably the safest option would be to get a french polisher or furniture restorer to have a quick look.

in case it is not a trapped water problem, i would spend a few quid on these before setting fire to the boat.

I don't know what boat you've got but it may be a sprayed laquer finish.

If the marks look whiteish rather than lighter wood you may be lucky and find that the discolouring is just in the very surface of the finish.

Try a mild abraisive such as Brasso. Very fine (0000) wire woll may also work and leave a less shiny finish.

Agree with LNL, if the stain is just in the top layers of polish/varnish etc and not penetrated down to the wood, you should be able work the top layers to remove and then re-finish with a polish / wax to uniform in.

Would also go with meths on a cotton rag to try first, but may end up with fine paper/wire wool etc depending on how hard the finish is you are trying to work down.

Many ways to remove, baking soda & olive oil, toothpaste etc, but you get the general idea, the hardness will determine best method.

Would it be possible to put some pictures up? else it's a bit of a haircut in the post.
Have fun!
