For whatever reason I've usually wiped fresh PVA off joints with a damp cloth. I've found with Blue Evostick that this causes a reaction that blackens the oak. Has anyone else noticed this, what should I do instead?

I think there must be some iron or steel involved somewhere. Perhaps a contaminated cloth or impure water,

On this build I decided to wipe off the excess with a wet piece of paper towel and on all joints where I did this there was a blackening of the oak, conclusion was that the contamination came from either the water or the sand paper used. I was using titebond 3 ultimate for the first time due to it's longer open time so went back to premium 2 but it made no difference.
