As a penetrating oil for rusted bolts it has simply never worked for me. As a corrosion preventer, it never works as it evaporates, motor oil does well.
I keep a regular stock of it, or the Walmart equal for hand washing.
GoJo type hand cleaners just don’t get grease, oil and general mechanic/farm grime from the pours, cracks and figure nail areas of older hands that are worn rough from mechanic/farm work.
Soak your hands in WD40, rub it in, then repeat with 409 GP cleaner, wipe hands dry. Hands will be nearly spotless. Finish up with soap & water.
You don’t have to scrub your hands & nails raw with a brush.
GoJo usually does fairly well for me after a couple of passes. I’ll try to remember your tip too. If there is a better way to do something, I’m usually interested.
Crisco or lard will quickly and gently dissolve grease from your hands. Follow up with Dawn liquid to remove the Crisco. Old school.
Good one- will try it.
I like Blaster for penetrating oil. It is curious how it was used for Atlas rockets with very thin— super thin stainless steel tanks to prevent corrosion from standing water (assume in a SSBN submarine).
