I have some nice teak furniture given to me by my parents when they moved. Nicer than the kind of stuff I can afford. Teak is great. One of the tables was starting to look worn on the corner that gets all the use, so I rubbed some “teak oil” on it (about a two minute job), and now it looks like new. While I had the oil out, I rubbed some on another table that had been stained by leaking batteries in a remote control. The stain has faded over time all by itself, and now you can hardly tell it was there. I’m not used to stains getting better by magic, or anything scratched looking good as new if you rub oil on it with a paper towel, or, really, anything decades old and abused by small children (such as myself) still looking pretty much perfect.
