I found an old bottle of WD-40 in my parent's house that I needed to oil a squeaky door.
I was thinking that the bottle looked vintage, but wasn't sure. I took a peek at the ad copy on the back, which says:
"Typical proven uses at home, on the job, on the farm, and recreational." Definitely vintage.
By the way, the label also says that the FDA approves its use in Food Processing Facilities.
Does anyone have a spare paper bag lying around? She could definitely use some.
