[peterw]

Found this on the web, a nice cheap way of doing it although would probably recomend it outside

Don't waste your time looking for any rust Dave - there's not a speck of rust on your car

[Denzle]

That looks brill "BUT"........

Rust forms by eating at the metal.  When the metal has rusted there is no way of replacing it, yet with these pictures the metal looks untouched and as new.

So all the stuff that has been removed must be sitting on surface of the metal and cant be true rust.  Confusing.

But a good idea for general cleaning of other parts. Will have to give it a try on something.

Edit:  Assuming the part will fit in the bucket!

The vinegar idea looks good, but it looks like it was just surface rust. dont think it would work on rust that has been left to eat its way into the metal.

I'll give it a try on a few prats though.

Loads of 'prats' at our work you can have to

Interesting stuff rust, having spent the last couple of weeks scraping, filing, grinding rust off the brake and suspension parts of my donor car I have some observations.
1. Rust is very hard, harder than the underlying metal.
2. The volume of rust is much greater than amount of metal eroded
3. Ferrous oxide dust makes a mess of your workshop!
Haven't tried the acid dip or electrolysis but I suspect both methods would take some time to have an effect on the thick, hard rust I am dealing with.
I read somewhere that rust is being looked at as a way of generating hydrogen (Fe + H2O = FeO + H2), also storing it without the high pressure cylinders, so I guess it may not be totally useless.

I've got an engine mount soaking in vinegar (out in the garage, far too smelly for the house).

I'll leave it soaking over the weekend and let you know how it turns out...

[peterw]

Crumbs, How much vinegar does that need, like 1/2 a tanker load!!!!!!

[peterw]

ooops didn't spot the word "mount"

I'm another one in favor of Electrolysis i'm a huge fan of it.
I did my sierra uprights and a few other pieces using that method, i had to run it off a car battery but i left each upright in there for 1 day each took the weekend and the results where amazing the 20years rust just fell off, you need to take a wire brush to it after to bring it to its best but thats just to clean any debris.
I looked at the vinegar  method but i can't stand the smell of it,
I'd like to try it but because it looks good but i'd rather not have it sat around stinking.

[Furore Phil]

Err yes - it was just a mount - only a litre of vinegar needed. Cheep stuff, not the wife's best balsamic 

You are right though - stinks to high heaven. Luckily I was out, and once rinsed off, the smell goes.

Ok, took the mount out of the vinegar - hardly any change ! Then I rinsed it off... large chunks of fust and old paint fell off, leaving sparkiling metal underneath ! Bit of scrubbing with an old plastic scourer and it came up a treat.

As I only had a small container I could only dop half the mount. I've stuck it back in, other way up.

Cons : Stinks to high heaven.
Pro's : Cheap (50p so far) and environmentally friendly (vinegar is a natural product)

After (more to follow after I have done the top half)

Wow thats pretty impressive!!

[Bulldog Bri]

Thought you said the car was OK apart from dust and a few cobwebs Bri?

[Furore Phil]

Hmm yes, think you'll need a little more than a litre ! Might get a bit wiffy though 

[Bulldog Bri]

Think I'll really just stick to the old wire brush.
