I'm cleaning this cabinet above the range/micro and noticed this mark on the back. I mostly keep cooking oils, vinegars, etc in here. Does this look serious?
Update: well it ain't pretty, but it shouldn't burn the house down. For anyone concerned, my electrician approves. Thank you all for your help today.
That it's melamine changes my thinking. Looks like a hot nail but guess it's not.
Gonna change my mind to stain or burn.
