Foaming PU adhesive gun cleaner is acetone. You get a big
can for far less than nail varnish remover prices.

You are probably OK with an Irish name these days. As long as you don't
have dark skin and a black beard, and ask "By the way, do you have any
peroxide too?"

people have gotten a lot more paranoid. My chemistry collection at age 9 would raise a panic today.

At a recent funeral, my brother recounted the time when he was 12 and
was able to buy concentrated nitric acid and other chemicals at a
high st chemist, to experiment with at home. (1960's).

Dunno... but since WD40 is not the same as white spirit, what does that
have to do with anything?

It's nearly 100% white spirit.

That's wrong:

https://en.wikipedia.org/wiki/WD-40#Formulation

25% mineral oil

12€“18% low vapour pressure aliphatic hydrocarbon

"50% 'aliphatic hydrocarbons'. The manufacturer's website claims this
ratio in the current formulation cannot accurately be described as
Stoddard solvent"

So the closest you could claim is a 50% solvent content that is similar
to (but different from) white spirit.



Check the MSDS, you will note its a different hydrocarbon composition,
and a much lower aromatic content than most white spirit:

https://cdn.wd40company.eu/wd-40/en-...CT-AEROSOL.pdf

Hydrocarbons, C9-C11, n-alkanes, isoalkanes, cyclics, 2% aromatics

https://www.barrettinepro.co.uk/uplo...e%20Spirit.pdf

hydrocarbons, C9-C12, n-alkanes, isoalkanes, cyclics, aromatics (2-25%)


plus white spirit does not evaporate to leave the heavier oil residue
like WD40 does.

With white spirit the solvent is the product, with WD40 in many
applications the solvent is simply the bearer of the product.

The small amount of oil doesn't help with adhesive dissolving.

That's not even wrong.

The mineral oil *may* well help dissolving adhesive - depending on the
type of glue. However its a straw man, since it does nothing to support
the assertion that its just white spirit anyway.


I see they've changed it to try to improve its performance for other things than water displacement. But it still scores bottom of the tests as lubrication & penetrating oil, so not one to recommend.

- it used to be just white spirit, honest guv!"

Is white spirit an effective water displacement product?

But it still scores bottom of the tests as lubrication & penetrating
oil, so not one to recommend.

Its a general purpose product. It will not necessarily compete with
specialist products in each and every category. However many people
value it since its a single can of stuff that in many cases will do the
job well enough without needing to keep a wide selection of solvents,
cleaners, penetrating oils and lubricants on hand.

Your words "It's nearly 100% white spirit"

I thought it prudent to point out that it isn't nearly 100% (or even
close), and it isn't technically white spirit either (even if it is a
similar petroleum distillate solvent).

The "little oil" is actually quite a bit (25%). The quantity of oil per
unit volume is in some ways less important, since when using it for
lubrication, the purpose of the solvent is to deliver it into position
from an aerosol can, and then evaporate, leaving just the oil.

oils tend to react over time, forming a tough gum. Some are a lot worse than others at this. I can't remember whether it's oxidation or polymerisation.

Dunno... but since WD40 is not the same as white spirit, what does that
have to do with anything?

It's nearly 100% white spirit. The small amount of oil doesn't help with adhesive dissolving.

What's the sticky residue that gums things up?

Andy

oils tend to react over time, forming a tough gum. Some are a lot worse than others at this. I can't remember whether it's oxidation or polymerisation.

WD40 leaves a sticky residue within minutes, as soon as the solvent
dries. I understood this is what makes it keep working - but it also
make it crap as a lubricant.

It's too fast to be oxidation.

oil can be sticky.
AIUI the high solvent content tends to wash lubricant out, that's a problem.
