Hi There,

The Coke trick sounds like the tip I've
heard using molasses for rust removal.

Good Luck!

We referred to penetrating fluid as skunk pi**. I never really believed any of the brands worked that well. What did work was a fine wheel cup on a angle grinder. If you go at the bolt until you see that line between the nut and the threads, it will come off. Otherwise it's hot wrench time, either heating or blowing it off.

Fait on their 124s to lower unsprung weight used aluminum brake disc calipers. Fine enough, except their bleed screws were steel. Unless you keep them free, they seized.In order to reuse the calipers after brake jobs, you could the calipers in pail of kerosene for a couple of days.

I've found the best way to loosen nuts and bolts is to use Never-Seize liberally way before the necessity of using snake oil. Especially on brake bleeder screws and lawn mower blades.

Does Never-Seize work on rusted fasteners?

If you are thinking of using it to FREE fasteners, no - it's a paste and would never even get in.

Applied to fasteners before assembly, particularly rust-prone ones like exhaust system bolts, and they will be MUCH easier to remove.

Hi There,

Living near salt water, I been using anti-seize on fasteners for
a long time. The most problematic are exhaust fittings and I've
lately switched to a high temp anti-seize (infused with Nickel).
It is supposed to be good to 2600°F and so far has worked on
the exhaust manifold stud/nuts on my son's Z28 Camaro.

For already rusted and frozen nut and bolts, I like Kroil. It has
provided the best performance of all penetrating oils I have used
so far. Sometimes it takes a couple days to get all the way in
there but given time, it will get in there.

I have read about the 50/50 mix of ATF and Acetone and have tried
it once on some bolts where I could immerse the parts in a small
can of the stuff and the results were encouraging. I am leery of
using this mixture anywhere it could contact painted surfaces.

Good Luck!

For years I used the same products that Webb specified.
Good stuff. Especially the Kroil.

I have never really had luck with any so called penetrating oils when removing rusted hardware. The best luck I have ever had was heat and once broken loose any kind of thin oil that will help with lubrication when turning the hardware.

I merely dipped into your site. Creditable! ( I don't know why people say incredible when it already happened). This heat disposition is very important and probably a secret. I know that you weren't using torches. Was it that the oxidation presented the very area of higher voltage at different frequencies? That is neat stuff and there is much more than that. Gosh I blew my mind thinking about how this could be done between fasteners and the base with digital readouts showing ... oh man. Back to heat and PB :)

My opinion?
You've come down with mental health.
It's absurd to assume oil will, in any way, break down rusted connections. Chemically it just isn't so! However, heat does, and oil, as you said, lubricates the assembly so it turns with less effort and, hopefully, prevents galling while dismantling.

I've (successfully) dismantled a lot of rusted connectors. Nothing like heat as a persuader. Heat, or a strong solvent (such as phosphoric acid).
