Hi! I am a newbie here. I have a mango wood table recently given to me. It is this one: https://www.cb2.com/blox-35x63-dining-table/s123863
The previous owner damaged it. He placed a yoga mat on top of the table when storing it in his garage. He then stacked a metal chair on the table (he thought he was protecting the table by first placing the mat on it). When he removed the chair and mat, he found these dark vertical marks on it. My guess is that when the metal heated up this summer, it leached plasticizer from the mat onto the table.
I attempted to clean the dark area with white vinegar and water. I noticed that some of that darkened area has a different texture and that when wet, it started to peel off with just the back of my finger rubbing on it. So, you'll notice there is now a lightened area in the bottom left corner. That was where I attempted to clean it. It seems that the darkened area came off, but so did the finish because of the lightness there. I attached a photo that shows what it looked like when the dark area started to come off (it kind of crumbled off?)
My guess is that the damage permanently damaged the finish and that the only course of action is to remove the finish and refinish it. Is that correct? I don't have any experience with this, and also I live in an apartment so doing this outside in a well ventilated area is not really an option. I can open all the windows and a sliding glass door next to the table if a chemical is used to fix it... but if that isn't sufficient, I may need to just leave as is until I move. But if there's an option to use Restor-A-Finish or something to just make it a little better in the meantime, I'd love to hear it.
Anyways, let me know what you think my options are! Thank you in advance.
