Green streak in maple (should I be worried?)
I added a coat of osmo satin oil to a maple cabinet and a green streak with dark spots appeared. I’m ok living with it as long as it is some natural relic of something to do with the tree that won’t spread. I just want to make sure I don’t need to be concerned about it spreading (ie a sign of some active infection/bugs). It almost looks like algae to me, but I’m not super knowledgeable in this realm.
Appreciate any help!
