tackle discoloration in wood.....

[robtheplod]

Hi All

 

We're having a shift around inside and removed a seat. Its revealed discoloration in the wood which is going to be a tad unsightly. Although it looks damp this seems historic.  I was thinking sanding down and varnish unless anyone has anything else i can try?  Would this sort of discoloration sand off?  thanks!!!!

I doubt it will sand out but you may be lucky that it is just the varnish discoloured. Either way you will have to get through the varnish back to bare wood, but be very careful not to sand through the veneer,  assuming that is what it is. A wash with a mild bleach solution may work, if not try using some oxalic acid. Again take care not to soak the wood especially if it is mdf or ply and follow the destructions on the oxalic acid.

You could try oxalic acid, which I think can be found in bar keepers friend, but I seriously doubt you will get that out.Probably came up from the bottom, through the end grain due to a spillage.

It says it contains oxalic acid, but not how much.Though Mr google says it only contains 10%, so may not have that much effect. I must admit, I have never tried it myself, but remember people recommending it for stain removal on wood.

Leave it for a while and the damp, which has been trapped by the varnish will probably evaporate.   Removing the varnish with stripper will speed things up. 

 

Do not sand the veneer itself.  Veneers are frighteningly thin and you will soon expose the ply behind the veneer.

They call it Traditional Wood Cleaner

I would have a look behind that panel as well if you can. There is a run stain on the flooring below that stain it COULD mean that there is a leak behind the panel.

If your tackle is being discoloured by wood you might need to see a doctor
