Check Wood Bleach labels in paint stores and fins one with Oxalic Acid
as only ingredient listed. Counteracts the dark stain in oak and
other woods with tannins reacting to metal in water.

I kept one of my plants in the hardwood floor area and forgot to place

with water and there were black stains on the floor?
Is there any remedy for it that I can do myself instead of hiring
contractors? I am very inexperienced in handy work, so please give me
thorough instructions to follow through. Your help will be highly
appreciated.

move the plant

let it dry for quite some time

sand the finish off and around it a fair bit

sand till most of the stain is gone, it won't all go away

bleach the area that is still stained

don't sand after bleaching, or you will have to do it again
