Hi,
I've recently recoated interior wood doors with a wood stain (oak).
After about 3 month started seeing white stains all around the coated
areas.

Is the door employed as an intern?

Any ideas?

Curious--is a "cool mist" impeller type humidifier, or an ultrasonic
humidifier in use in the house?

These leave mineral dust around if used with tap water...along with
other nasties.

Best Regards,
