Dave 2 Posted September 27, 2017 Report Share Posted September 27, 2017 Hi all I have a historic problem with water staining to the roof panels around the vents. This was due to the previous owner winding the mushroom vents up as far as they could go, looked like umbrellas when I viewed the boat. The boats been sorted out and the only thing spoiling it is the dark water stains around the vents in the cabin. The panels are medium oak any ideas would be appreciated.

Mike Jordan Posted September 27, 2017 Report Share Posted September 27, 2017 The only methods that spring to mind are - bleaching the oak veneer with oxalic acid ( suggest you google the name for details and safety considerations) or perhaps much easier, consider painting all the roof panels with a suitable light colour to cover the staining.

Robbo Posted September 27, 2017 Report Share Posted September 27, 2017 (edited) Toothpaste and brush may work for dark stains. Trouble is that dark stains means the water has reached the wood, so you may have to remove all the finish and then bleach.

That’s the active ingredient in Barkeeper’s Friend, Mike. Link to comment Share on other sites More sharing options...
Dave 2 Posted September 27, 2017 Author Report Share Posted September 27, 2017 Hi Yes the trouble is the wood has been varnished I’ve tried oxalic acid no joy there. Link to comment Share on other sites More sharing options...
WotEver Posted September 27, 2017 Report Share Posted September 27, 2017 Then I’d try a chemical stripper to remove the varnish first. If you make it worse then you’re back to the replacing or painting choices. Link to comment Share on other sites More sharing options...
Mike Jordan Posted September 27, 2017 Report Share Posted September 27, 2017 (edited) Sorry, I failed to mention that you will need to strip off the varnish prior to trying the oxalic acid. Hence the reference to painting being easier. Hi watever You are right, it's the basis of a number of bleaching and metal cleaning products. I don't think it's a good idea to use it before having a look at the H and S details. One of its drawbacks to my mind is that the crystals look just like sugar, on the rare occasions I've lent my box of crystals to a boater it's been the whole box complete with all the warnings on the side. I did read of an instance of a pub landlord drinking a fatal dose thinking it was gin. Not sure if the tale is true but it makes me very carefull! Painting the roof panels and superstructure with a light colour is quite common now, I think it makes the boat feel more spacious and takes away the coffin like look that you tend to get with older varnish which has gone darker.

Agreed. OP is unlikely to get anything like a perfect oak finish now, whatever he does. Link to comment Share on other sites More sharing options...
