When I just bought my Civic (it was used), I had to get a new center console https://www.carid.com/center-consoles/ . And to have it installed, I really spent a lot of time and effort removing those two rusty bolts, which attach the console to the floor. So finally I had to spray some WD 40 there to make these move, and only then managed to unscrew. Looks like they rust due to moisture getting onto them from underneath, so it is the best place to apply WD40.
