From one BaldCefn (Its Welsh for Kevin) to another baldkev, many thanks for this information. It's worked brilliantly. I virtually did it as you recommended. and so pleased with the results. Thanks to everyone else who sent their advice. Its very much appreciated.

It also looks like ink to me. Oxalic Acid or Liberon Wood Bleacher may help if it is.

...for the very first time recently on the lid of an old gramophone. It had a black water damage mark which I manged to get out with Oxalic acid and it looks OK. I then added maybe 50/ 60 coats of shellac in several sessions, however where the stain was the grain must have lifted so I'm left...

Oxalic acid is usually quite affective on oak stains but mot sure about the baking soda so perhaps a test is in order.

...and holes where it’s nailed together so to get it looking perfect would be a lot of work colour matching filler etc. Good tip about the oxalic acid - I might give that a go, thanks. I have thought about that, we’ve got kids but the carpet has been up for about 6 weeks and we’ve been ok so...

If it's a oak surface but not solid oak, then veneer rather than laminate. Laminate tends to mean a synthetic material. But for removing a dark stain in oak then oxalic acid does the job.

...of the wood back up, I have tried bleach in the past on a couple of small projects without success and Rustins A and B was recommended to me, however I haven't used that as yet. I was really wondering if anyone had any experience of using Oxalic Acid themselves and how they'd found the...

...change. I phoned them and he said he has never had that before etc, and couldnt help. After much research and testing, a mix of coats of oxalic acid and peroxide brought it close to retrievable. A couple of days of sanding and i was in business. That was honestly the most stressful thing...

...to contact with iron (I’m guessing wire wool) the only way of getting rid of these is to either sand through them or to use a solution of oxalic acid. You can buy oxalic in two forms, crystals which you dissolve in hot water or you can buy it in solution, the only one I know of is ‘wood...

Only observation I would make is that I wouldnt use wire wool until you have had a practice on something expendable. It IS a good way of doing it, but its also very easy to go too far and go right through the finish if you havent done it before, especially on edges.

Thanks Sgian, you make excellent points. Much appreciated.

...off all dirt, green mould and the greyness and takes the oak back to a natural colour. Some people do this with buildings, and also use oxalic acid. It works but again is a job to do. I jet wash our garden furniture every year. It restores it cosmetically but does raise the grain and is...

I applied Oxalic Acid to a sideboard about a week ago to remove water stains (mixed in 1:6 ratio with warm water). I forgot to neutralise it and then sanded, applied white spirits, oiled and waxed. There was no issue with applying the oil and the sideboard looked great. Over the weekend I...

Does the oxalic acid work on all woods?

Yes dipping often a disaster. I've had people bring in what looks like a heap of salt encrusted driftwood found on a beach and saying "can you put this welsh dresser back together?" 😳

Makes sense thanks

...I’ve just built an English Ash table which had lots of such marks infact some of it was close to being olive ash but it just adds to the character. If you don’t like it you could try removing the staining with oxalic acid or failing that if you want a very white Ash go for American White Ash

...throughout the small pores of the timber's surface. I suspect the bleaching options suggested by others, whether you use A+B bleach or oxalic acid, or both, won't remove the black colour from both the wood species. If either or both of the bleaches work then you could follow up with a dye of...

Well done that man! The start of an extensive market garden business! The green on potatoes contains oxalic acid, and is poisonous. Everyone panics over this, but if you eat an entire plateful of green chips, you may get a slightly upset stomach. I just clean mine up with a peeler and get the...

I used to bleach a lot of sycamore using oxalic acid but could never get it pure white,it used to have a pinkish tinge.Holly can vary,I have some pear that is quite white but it does tend to split if not dried very carefully.
