SoySaucePrinterInk3-in-1 oil?
CompactFlaxFor me, there’s nothing wrong with some used light motor oil. Can’t use it if your car is a diesel. Also consider rustproofing oils, with a rubon/off coating. I’m trying linseed oil as a natural alternative to motor oil but even boiled it sets up so it needs to be a crazy thin coat.
Umm linseed oil is an oxidizing oil and therefore not a good choice since as you’ve found, it will ALWAYS harden…
Ballistol Universal Oil is German or Austrian I think and works great in place of 3 in 1 and many more spots. Thousand and 1 uses.
Although it can be tricky to find everywhere, most sporting goods shops with a hunting section will have it, or Canadian Tire does. Comes in spray or liquid. Ask your local hardware store to start carrying it!
