Brake Fluid for Cleaning Bolts?

Any reason not to soak old bolts in used brake fluid, wipe
them with a rag, apply, say, anti-seize, then re-install?

My concern would be the water absorbing properties of brake
fluid. But if others routinely do this, then I won't be
concerned.

TIA

The biggest reason is WHY. Brake fluid is not particularly good for
this anyway. You could use a regular degreaser or kerosene. I'd just
spray them with Liquid Wrench or something similar. People have used
all sorts of things including vinegar, but I prefer regular old
petroleum distilates.

Because (1) it's darn effective at removing, for example,
paint; and (2) presumably it has some lubricating
properties; (3) beats just throwing out old brake fluid.

Actually, it is not very good at removing paint...at least, not most paint.
It might
damage auto finishes, but without a little caustic added to it, it isn't a
powerful
paint remover.

It slicks up bolts, but - as mentioned earlier - picks up water and could
promote
rusting, I guess.

I'm not sure why you'd want to do this; brake fluid also eats paint
which is not a concern on bolts, but can be a concern if the parts the
bolts connect are painted. Also there are better parts cleaning
solutions available, kerosene works well and is cheap although it is
more easily flammable so more care should be taken.

Bad idea if you ask me. If you want to soak them in something, use old
motor oil. Personally, if the bolt is that far gone, I replace it. I
always use Anti-Seize on most of my bolts.

Don't even bother. He wants to use brake fluid and that's what he will
use. He only wanted us to tell him how great it would be. He knows
everything and simply wants validation.

Brake fluid acts as a great penetrating fluid in a pinch. I have had to
take some out and trickle into a rim's holes to get the rim to come free
from the hub. Driving on it with loose lug nuts and using the back end
of a log splitter maul didn't budge it but a soak in brake fluid let it
pop loose.

It seems to eat rust, never thought of using old fluid on my old rusty
nut and bolt collection that got caught in a rainstorm. I think I might
try it and see. I will post back about it.

I won't be using brake fluid if no one else uses it, because
of concerns about the water absorption. I really don't know.

Congratulations, anyway.

Lots of folks report similar stories to yours, but no one
talks about routinely using it to clean old rusty bolts. So
I'm hesitant, like maybe I'm missing something.

Maybe the stuff is so hard on the hands that people avoid
it. Dunno. Just thought I'd ask, since I'm in the middle or
a suspension renovation job and have come across some pretty
beat up nuts and bolts (many of which I'm replacing).

what's being missed is that it's a great rust promoter. put some bolts
in a paper bag, saturate with brake fluid, then leave out in the garage
a while. the only time it can be used in contact with ferrous metals is
where it's sealed and moisture absorption is minimized. otherwise, it's
a great way to return iron to its original ore.

I'm confused. Are you really looking for information or just looking
for someone to justify what you have already decided to do. Someone
gives you several well thought out reasons why it isn't a good idea and
you respond with your own pre-conceived justifications.

If you want to use brake fluid as a cleaner then go ahead but it is a
poor choice. Just don't ask for opinions if you don't want to hear
them.

Is there any other chemical that will remove paint from plastic without
damaging the plastic? Brake fluid did a good job stripping the paint
form my ABS/polycarbonate wheel covers.

Depends on the plastic, and on the type of paint. Brake fluid is not
normally
a good paint remover for GOOD paint.

Acrylonitrile/Butadiene/Styrene is a pretty tough polymer. Used in athletic
helmets
and a number of other high impact applications. Although it is not
impervious to
solvents, it often tolerates them pretty well without softening.

I think you are misinterpreting the question. She is asking: "is this idea
going to do something bad rather than the good I am hoping for?" and seeking
the experience of others. I believe learning from the experience of others
is a good thing and the main reason we are here - most of us, anyway.

For myself, I've never tried it and am curious how it works out. Since Elle
doesn't know everything, and knows she doesn't know (thus the question) but
has a good reputation here it has my interest.

Yes, that's precisely it.

Thanks. But on this one, I am not inclined to experiment. It
just seemed like people would do it a lot, or they never do
it. In which case I don't want to be the guinea pig. :-)

Makes no sense.

Time for my 0.02 ...

Yes, water absorption IS the problem, as this causes the normally inert
fluid to become contaminated with acidic compounds. Leaving a residue of
brake fluid will cause rust to start in double quick time as the acidic
compounds expose raw iron to oxygen. If you doubt this, look what happens
to, say, a cast iron clutch slave cylinder that leaks: it gets covered with
a layer of rust.

Much better to replace a rusty bolt with a new one, and use an anti-sieze
compound. If you must wipe bolts with something, use WD40 or engine oil.
