Barley twist table legs to natural oak finish.

[torquecurve]

Hi,
I need to remove dark stain from 6 barley twist oak table legs. Regular paint stripper had very little effect and hand sanding isn't working.
Are there a methods, product or tool attachment I could employ to get through to the natural oak finish of the complex shape.

thank you.

Oxalic acid will remove the stain :wink: or you could try wood bleach comes in parts A+B But will lighten the oak as well
