Depending on the application, I use 1 of 4 methods. Dry graphite in a small tube can be blown (squeeze the tube)into tight areas, and will not collect dust. Light machine oil (3 in 1) for easily accessable areas. Petroleum jelly is a very light grease, where it is more appropriate. On record changer mechanisms, I use a light duty graphite based mixture in a tube.
