Does anyone have experience removing pink stain in solid white ash lumber? I'm not sure but I would guess that it is a fungal stain (it is not sticker stain). We cut the wood at a sawmill and the stain was visible immediately. The wood has now been air and kiln dried and the stain persists.
From contributor R:
You might try a wood bleach on the offensive areas or even a thinned out Clorox laundry bleach might work. Carefully apply the bleach with a Q-Tip and keep an eye on the bleaches reaction. If the pink stain is superficial it wonít take the bleach (either of them) but a few minutes to work. If you use a wood bleach for this job, see if you canít find the A-B Bleach made by Wood-Kote. It used to be called Speedeway but they since sold to Wood-Kote. The beauty about this bleach is that it wonít leave a foamy mess like some of the other A-B bleaches do. If the stain youíre objecting to was on maple, it would be identified as spalted maple and itís actually quite prized for some applications.
The fungus is dead after drying above 130 F. It might be best if this discolored wood was considered to be enhanced character and then sold at a higher price (similar to wormy chestnut and spalted wood). It is possible that the sanding dust will be an allergen (severe) to some people, so be very careful.
