As someone else stated, WD-40 is a solvent and a degreaser. It is designed to displace water. In fact, for bearings which need grease, WD-40 can remove the very thing that is keeping the bearings from wearing out! If the fan is very old and no longer works properly, it just needs to be replaced. |

Sometimes it is really complicated replacing them with a danger of damaging stuff, if you have no routine. Then using something to spray is easier to fix it for some time. It helped in my cases, even though I will definitely try something else next time ..
