#PSA For a sticky lock/knob, don't use WD-40 or 3-in-1/household oil ~ use a graphite spray specifically intended for the purpose 👇. Other oils will tend to hold dust and dirt in place, and thicken in the cold and will gack the works up worse!
Sidebar: amazing that the black overspray I just wiped off the outside of my now freely moving latch, under the right temperature and pressure conditions, will become a diamond. #science #ThisAmazingWorld
@CLManussier this stuff is great; made the door locks on my 30 year old truck work like new
