The unexpected legend of WD-40

"That would make WD-40 like the formulation above. The kerosine is the solvent, the tallow oil and lubricating base grade provide the means for the fluid to displace water from surfaces and, when the kerosine has evaporated, leave a thin, protective film on the surface that provides temporary corrision protection. It is possible that it may have some solid lubricant in it ( PTFE,Graphite,MoS2 ), but I suspect there would not be enough to provide any useful lubrication - and thus should not be used to wash "proper lubricants" off bearing surfaces, chains etc.. "
There are not many hints that the whole video is AI-generated. The voice sounds mostly excellent (only the harsh sibilants are annoying on headphones), the visuals are great and most imperfections look like deliberate decisions. It is impressive/scary to see how high the quality of this stuff got. A few weeks ago, I was complaining about how utterly bad all AI-generated audio content is. Now it took me 6 minutes to watch and listen until I noticed.
Why does it matter?
The story of WD-40—how a simple formula became a must-have for homes, garages, and industries worldwide.
Using WD-40 in residential applications often results in inhalation of aerosolized particles and injestion/absorption of residue on skin.
How can a consumer make an informed decision about using WD-40 without knowing what it's composed of?
I just search online for the MSDS for the product.

Just use common sense, assume all aerosols are toxic, then temper your concerns by remembering the frequency of your exposure to that toxin, and compare it mentally to how much garbage we inhale walking around the average city.
