WD-40 can be useful, but I've found several problems with it that make me hesitate before I grab the can and spray.
- Attracts dust- I once used it on an office chair to stop squeaking. Worked great, but a month later the mechanism of my chair was furrier than a maine coon kitty on Rogaine. Not only that, but...
- Doesn't work for very long - The aforementioned squeaking chair started to squeak again a month later. Maybe it was because of all the dust? I don't know, but machine oil was effective for much longer; it was just more difficult to apply.
