Last night I moved a houseplant that was on my engineered hardwood floor. Found this black stain - not sure if it’s mold, but clearly water stain / damage. Tried applying some diluted vinegar and this morning it looks like the second picture. Not sure how much of it could just be drying out vs. an effect of the vinegar. Anyone have any recommendations for next steps? I’d like to dry to treat it, but am willing to replace the boards if needed. Thanks!
