The caveat is use the right one for the right job. There's a meme that if its not moving but its supposed to you need WD-40... well you need Silicone WD-40 or any silicone based oil like for a garage. If you use regular WD-40 in a garage it is a degreaser essentially, and your squeaking goes away momentarily, and then comes back. After I learned this, you have no idea how much silicone WD-40 I had to put in my garage to make the squeaking stop for good.
