Rubbing down solid oak door - how far?

Postby nblain » Sun Jun 17, 2018 12:48 pm

I am in the process of trying to rub down an external solid oak door that has suffered from the ravages of the weather and neglect and was planning on then treating it with Osmo oil 420.
My question is, how far do I need to rub it down? The attached pictures show that I have got all the grey stuff off the flat surfaces, but the there is still some pitting in the grain. Do I need to keep going, until all the pitting is gone?
From the overall view, you can see areas where I have done a bit more work and it looks clearer.

TIA

Try cleaning it off with some oxalic acid diluted with warm water, that should get rid of any black marks and revive the timber.

You then need to neutralise with water, let it dry and cut back the raised grain prior to finishing

Many thanks. From what I've read, oxalic acid gets rid of the black marking by bleaching the wood?
