well use lemon juice on the stained area
obviously a fresh lemon
it will take stains etc out of the wood, leave to dry and carry on as normal, flattening etc

You can buy a two part wood bleach for this sort of job, but you need to take care not to turn the wood white.

yes we all know you can get 2 part, 1 part, domestic, industrial bleachs.
but all at an expense and very little is used.
so my route of lemon juice is as good, more friendly to the timber, and a lot cheaper

Seconded, its really an excellent method to remove stains from wood. Its cheap,natural and smells great. Good to get away from chemicals,which can over bleach the wood. Good tip Dennis.

I just tried this. It required one large lemon per side. A third would have been enough to do the back doors if I hadn't already oiled them. The effect was negligible, but then I'd already used Oxalic acid and Cuprinol preservative on the wood and just thought I'd make a last ditch effort to get those remaining stubborn stains out before oiling it.

I have side, if that is the right word, with Alex. I went for the Oxalic acid approach and am very happy with the results. I did try the Leom Juice method first and didn't notice any results, so I went the chemical route, but that was just personnal preference.
