| I'm unsure what your definition of "cheap" is for WD-40 but I find it to be very overpriced. If I need a universal lubricant that is readily available and cheap, I just use used motor oil. |

| I thought WD-40 was more a solvent than lubricant |

| ▲ | steve_adams_86 5 hours ago | parent | next [-] | | Yeah, it mostly evaporates and only leaves a thin film behind. It's better than nothing if there's no lubricant in place, but will actually make things worse if there is a functional lubricant in place. | |
| ▲ | Telemakhos an hour ago | parent | prev [-] | | The WD in WD-40 stands for "water displacer." It makes water go somewhere else. Secondarily, it is a solvent, and it's great for dissolving glues, like the glue used to affix government-issued tax licenses to automobiles. It's not really a lubricant, but in a pinch it can temporarily function as one. I like Swiss army knives, but they collect lint and gunk from my pockets. I use WD-40 to dissolve gunk, and to drive out water after an ultrasonic bath, but I lubricate with the light machine oil used for barber's clippers. |

| Used motor oil isn’t sold in aerosol cans with a little red straw for precision application. You aren’t just buying the liquid. |

| Motor oil doesn’t spray too well. (Yes, you can buy bulk wd-40 liquid and put into a branded or unbranded sprayer) |

| Isn’t that carcinogenic? |

| ▲ | sidewndr46 6 hours ago | parent | next [-] | | Isn't a pretty wide range of products you'd use for this? I guess vegetable oil isn't and it works fine. Fluidfilm I don't think is either. I wear PPE for this reason however. | |
| ▲ | legitster 5 hours ago | parent | prev [-] | | Only if it's used and only if it's ingested. Clean motor oil is not actually that harmful if swallowed - it only carcinogenic because of all the metals and carbon it builds up when in the motor. | | |
