wd 40

[dr. d]

they market it as a lubricant and people use it all the time as a lubricant, but end up dissolving the grease on bearings and bushings instead LOL

"misleading marketing."
"anything to make a buck."

but perhaps it got this sort-of reputation, because it loosened stuck bolts and joints.
folks then made the mistaken conclusion that it was a lubricant, "dahil pinadulas ng WD40 yung stuck-up bolts ko".
and so the legend grew.
