I use kerosene or gasoline to unclog instead of wd40 For most general purpose use, I use white Lithium grease. If it's metal to plastic or plastic to plastic contact surface: silicone oil/grease (mostly in 3d printed parts) If it's metal on metal and in dirty environment: I use dry teflon lube or ceramic lube (mostly on my mountain bike and 3d printer lead screw) If it's heavy metal on metal where it can heat significantly: MolyD grease or graphite grease
