Hi there, so I've been living in my apartment for almost a year now and I've been preparing to move out. I pulled up my rug by my desk and noticed that the hardwood floor was damaged. There are definitely scratches, but I have no idea how that is possible given I've had a rug there for a year. I believe it may be mold damage given that the underside of my rug had some mold where the damage on the floor is.
Ripping up the hardwood is not an option. I am so far trying to use a light gloss to make it look half decent but it won't help the darker spots. Does anyone have any suggestions on what I could try to fix this?
Thank you in advance.
