Kroil penetrating oil works wonders on rusted and frozen metal and I think better than WD40.
Irritable bowel syndrome.
I always keep a can but don’t use it as much as I used to. Ever since I got an oil can with a spout, I have used 30 weight motor oil for lubrication and rust prevention. Really cheap and works very well.
I remember when it was less than a dollar a can. The last one I bought was nearly $5. They do have a much nicer spray nozzle now.
It’s a great cutting fluid for machining aluminum.
I don’t like duct tape, and don’t really have a use for WD-40.
I agree with the posters who use oil where oil is called for.
Bob Vila is an idiot.
I know people who say that helps their arthritis.
It burns way to much for a personal lubricate bacon grease works best
Silicon spray is better; it doesn’t attract dirt as much as WD40 or even oil.
Food grade silicon for plumbing.
Don’t use wd40 for locks in winter.
Use oil. Oil stays.
A hint for badly rusted nuts: remove gross rust with a sharp pick/wire brush, spray wd40 on the rusted bolt and then give the bolt/nut a sharp whack (don’t hurt the threads), give it time to soak in and repeat.
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.
WD40 is a menace. It isn’t as good as oil to lubricate. It isn’t as good as Kroil for penetration, the only thing it is good for is if you spray a ton of it on the underside of your rig, when you get done mudding, the mud will come off with a pressure washer.
Ah, that would be water dispersant (thus the 'WD'; 40 is the number of the formulation: Water dispersable, 40th attempt).
You can spray LPS, a WD50 competitor, on your tires and it will loosen all the little pebbles caught in between the treads.
Penetrating Oils
Machinist’s Workshop Magazine recently published some
information on various penetrating oils that I found very interesting.
Some of you might appreciate this. The magazine reports they tested
penetrates for break out torque on rusted nuts.
They are below, as forwarded by an ex-student and
professional machinist. They arranged a subjective test of all the popular
penetrates with the control being the torque required to remove the nut
from a “scientifically rusted” environment.
Penetrating oils ...........
Average torque load to loosen
No Oil used ................... 516
pounds
WD-40 ..................... ... 238 pounds
PB Blaster .................... 214 pounds
Liquid Wrench ...............127 pounds
Kano Kroil .................... 106 pounds
ATF*-Acetone mix............53 pounds
The ATF-Acetone mix is a “home brew” mix of 50 - 50 automatic
transmission fluid and acetone. Note this “home brew” released bolts
better than any commercial product in this one particular test.
Our local machinist group mixed up a batch and we all now use
it with equally good results.
Note also that “Liquid Wrench” is almost as good as “Kroil”
for about 20% of
the price.
Steve from Godwin-Singer says that ATF-Acetone mix is best,
but you can also use ATF and lacquer thinner in a 50-50 mix.
*ATF=Automatic Transmission Fluid
Liquid wrench is the best value.
Kroil is best but very expensive compared to Liquid Wrench.
WD40 is the lousiest “penetrating oil” ever. Dog piss would work as good.
Water Displacement compound 40. Developed for Atlas booster rockets as anti-corrosive. Not patented because of proprietary composition not to be disclosed- interesting concept, that one.
From the WD 40 FAQs:
WD-40® Multi-Use Product can be used on just about everything. It is safe to use on metal, rubber, wood and plastic. It can also be applied to painted metal surfaces without harming the paint. Polycarbonate and clear polystyrene plastic are among the few surfaces on which to avoid using a petroleum-based product like WD-40® Multi-Use Product.
There are no Mil-Specs for WD-40
Does not contain fish oils of any kind.

[slinking away.....to take a nap....old people like me, need naps]
I drench all my new primers down REAL good with WD-40 when I’m reloading.
I think I may be in trouble again.
