I rent, so the amount of money and labor I am looking to invest in my floors is small. That said, there are a number of spots where the hardwood has a sort of "dead" look that I wouldn't mind touching up if there is a straightforward way to improve the situation. The floors don't have to look new (clearly that is not going to happen), but maybe these spots can be less visible than they are now. Is there a relatively simple approach?
Related question: even the parts of the floor that aren't discolored are pretty beat up. Any recommended products for just improving the overall shine and appearance?
