Furniture, Wood and Cabinetry Finishing - Damaged Hardwood Floor.....with an iron

Hi,

My friends and I were making some t-shirts with iron-on transfers, and we needed a hard surface. Me being the genious of the group suggested we use the hardwood floor with a towel over it for protection.
The shirt turned out great.
The floor however, now has a raised mark or where we ironed the shirt. And the towel has a stain where the lamanent from the hardwood floor came up.
The surface of the floor is also very rough to the touch, whereas the rest of the flooring is extremely smooth.

Does anyone know how I can repair this? I don't know if I just need to put some oil on it and buff it a little? Or perhaps Old English Oil?

We quickly stopped after we noticed the damage. So it is a small area that needs repair.(about the size of an iron.)

Thanks,

If this an engineered floor, that is, laminate over substrate, the laminate may have separated from the substrate necessitating replacement of the damaged section.

The home was built in the 1940s or 50s. The wood looks like it's been there a long time. You can't notice the rough spot unless you put your hand on it or look at it at certain angles. It is ever so slightly lighter than the rest of the floor.
Isn't there a way to buff it or something?
Is replacing the damaged boards something a non-professional can do? Or should I hire someone to come out?
I can take a digital photo of it if that would help.

You probably melted the finish. The iron acted like a heat gun or torch when used to remove paint. It will need to be sanded and refinished. Hard to say if it would be feasable to touch up and not show.
