Nice!

If you slowly drip your acid into some potassium permanganate, you can make chlorine gas lol

Be careful though, it chokes ;)

hmmm - now I've got some brick cleaning acid solution (about 18% hydrochloric iirc) and some pretty shabby looking wheel bolts. I wonder what'll happen if I put the two together?

Tune in tomorrow night for a progress report

Well - that's one done and a pretty good result I think. The bolts were never shiny, even from the factory but the coating of rust all over the heads is really unsightly, but I reckon about an hour dangling the hexagon heads only in the acid has returned them to what is probably their original factory look.

after





I need to look into something to "fix" the surface now to prevent future discolouring (if I keep repeating this I'm going to end up needing a smaller sized wheel brace) :biglaugh: :biglaugh: :biglaugh:




On going back to the car - to do some more bolts I spotted that the cleaned bolt has started rusting already - it can only be half an hour since I put it on - I will definitely wait until I can get some kind of rust preventer on them.

Nice 1 alot better then being grubby black . What you need to do is dip them and when clean dip in water then dry them off quick with a hair dryer or heat gun then a quick spray with zinc silver the paint will dry instantly and they wont rust again and look like new :thumbup:

That's probably chlorine gas, it's what they used to kill people in WW1.

This, from the Wilfred Owen Book of Car Maintenance:

Dim, through the misty panes and thick green light,
As under a green sea, I saw him drowning.
In all my dreams, before my helpless sight,
He plunges at me, guttering, choking, drowning.
If in some smothering dreams you too could pace
Behind the wagon that we flung him in,
And watch the white eyes writhing in his face,
His hanging face, like a devil's sick of sin;
If you could hear, at every jolt, the blood
Come gargling from the froth-corrupted lungs,
Obscene as cancer, bitter as the cud
Of vile, incurable sores on innocent tongues,
My friend, you would not tell with such high zest
To children ardent for some desperate glory,
The old Lie; Dulce et Decorum est
Pro patria mori.


I'd go easy on that stuff, just so's you know, like.

I hear you fella but worry not its only for my dip tank as i no longer have a shaker box as it caught fire and burnt my wheels :paranoid:

But as things go on the lethal list my wife is much like Hagrid from harry potter and since she has not killed me yet i doubt the Acid will :jester:

Thanks for that M. I may try that, first though I just ordered some Loctite Rust Cure off ebay (only £3.99) I'm going to try one with that - I understand it may turn them black (or maybe some other random colour) if it looks better than the the rusty ones I'll go with it.
