check this link out! i tried it on some injector line holders and some rusty wast gate line nuts and bolts and it works great makes it look like new metal!
best to let soak in the malt vinegar ! the longer the better results like 2 days if a lot of rust!http://vwcaddyforum.com/showthread.php?t=17860

Pretty impressive. Who would have thunk.
-
Wow. :shock:
Time to stock up on malt vinegar...
-
i wanna try it in my sonic cleaner on some injectors and see how new it makes them? and if it speeds up the process?
it does give it that new metalic look like in the pics! unbelievable !!
Duane :shock:

What kind/brand of sonic cleaner do you have? Just curious, looking at picking up one for myself.

it's a harbor freight special! small about 32oz good for cleaning the ol'ladys jewelry! once a week i'm her jeweler too :D !

Wow. I wonder if white vinegar works aw well. I don't think I've ever seen malt vinegar in any store I've been to.
-
try it on some rusty parts and report back! be nice to know?

I've seen white vinegar in 1-2 gallon jugs locally... I imagine that it's the acid in the vinegar that's working the wonders, so white should work.
-
That is impressive. Maybe we should fill up our varsol tanks with malt vinegar. :)

I´ve used citric acid to clean out rust. It does very good results. Test piece (http://www.kotinet.com/matti.farm/Totke/17072008.jpg). Phosphoric acid would be even better. It leaves phosphate to surface, which is good contact to paint. I think POR-15 Metal ready is mostly this. Klik (http://www.kotinet.com/matti.farm/Valiant/Moottori/P9080182.jpg)

Wooowww
That's so cool
I'm weary to eat malt vinegar now :P
-
I've been told that molasses will do the same thing, albeit likely more slowly. Guys on metalshapers.org use about 7 parts water to 1 part molasses. Takes about a week to remove the rust.

Wooowww

just imagine how that will clean your arteries though :wink:
i think this guy uses a similar product to clean out ones arteries from all the plaque (build up of minerals, especially calcium)

In grade 6 i did this science experiment to see what acidic properties soda pop had so i hung a galvanized nail in sprite, coke, diet coke, root beer, and so on
I used water and vinegar as a control. After about 6 weeks there was no trace of a nail in the vinegar if i remember correctly. The worst pop was tonic water i think? or diet coke...
regular coke/rootbeer i remember was the least alarming.

you know your young when you can remember grade 6! *** i can't remember my college days! :cry:
there was good drugs back then tho! :shock:

I'll take the meth these days anytime. :roll:
Good find on the malt vinegar! I'll have to try it out sometime. But I'm sure regular vinegar would work as well. I remember, as a kid, cleaning pennies as a science experiment. Turns them into super shiny copper pennies again!

LOL! While I wasn't there, I listen to a lot of music from back then. Must have been some great drugs. "She walks like a bearded rainbow"?!?!?!

A classic Cream tune if I recall correctly, good stuff! :D

i'm telling ya they were good i don't even remember that! :roll:

Thats how you know they were good.
Like they say: If you can remember the 60s you wernt there.
I need to talk to a friend of mine about some industrial sized vinegar.

Brown ketchup makes a good cleaner, and you can paint it on
-
Well, I'm sooooooo sorry that not everyone on the forum is an old geezer!!!
I'm just kidding.
I remember it well because it was interesting to think/see how corrosive citric acid is.

brown ketchup :shock: man you guys eat some wierd *** over there?
our ketchup is red like a tomato over here!
if it's brown! wouldn't that mean it's spoiled or bad?
Duane

Perhaps it's HP sauce?
-

I'm not sure what exactly "brown ketchup" is, however the wife and I were in Ireland for 2 weeks last month and they had "brown sauce". Let me tell you, a liberal application of brown sauce on a basket of pub chips (fries) is just the ticket!
Now that we're back in the states I'm craving some of that mysterious brown sauce. :(

coca cola wil decompose a dead pig in days!!!!!!!! :D :D :D :D :D
........if you ever need to get rid of a dead pig that is. 8)
-
And a couple of pigs will get rid of a dead body.
Wait, did I just say that out loud?

Yea HP sauce, or Daddies sauce,
I wonder if WI Encona Scots Bonnet sauce would work? Just blow your socks off if you rub it in your eye I think.

i been messing around with this stuff! i could not find large amounts of malt vinegar so i tried the white or clear vinegar that comes in gallon jugs! well it works too! so i got some injectors sitting in there and we will see how they turn out? does work best if the parts have been fully degrease of oil!
allows the vinegar to penetrate the rust !
Duane
-
Good to know, I think all I can find in quantity is white vinegar too. I would have figured the vinegar would eat the oily grease too. I plan on leaving my parts soak for several days, not just overnight. Hope to do some shopping today or tomorrow for bins and vinegar. Gonna hit the "foodstamp stops" for cheap vinegar!
Brendan

Are you guys sure this is a wise idea to use on tolerance parts like pumps? The acid will be eating away some good metal too I would assume. Maybe a good way to enlarge nozzle holes...?
-
I bought 4 liters of vinegar today to do manifolds and similar parts.
I don't think you need to worry too much about fresh material coming off unless it starts to tarnish things. Rust/corrosion may be harder than the actual substance...
for example, aluminum oxide is much harder than aluminum but i rubs off with your fingers. I think the vinegar, citric acid and so on will take the corrosion off and leave the rest alone unless you leave it in there long after all the corrosion is removed.
-
i wish someone with a background in chemistry could chime in... but i would almost guess that the acid only attacks the aluminum oxide, because of the oxygen... and leaves the rest alone, but eventually acid can eat through many things...
-
I'm not a chemist by any means, but I think it may have something to do with where a product is on the PH scale. Vinegar is acidic but we use a cleaning product at work that is alkaline, so to the other end of the PH scale, and it will actually remove anodizing from aluminum. and start corrosion on copper and even plated metal if left on too long. If applied and washed off within 10 minutes, there is no problem with this, and it removes all oil residue. I suspect the vinegar works in a similar way in that it is time sensitive. A short application probably wouldn't even get rid of the rust, but if you left a part in it for 2 weeks, it might damage the base metal.
-
i been messing around and found out that you should not leave in no longer then 72 hours! periodically hand wire brush the pieces!
if left to just sit it will start eating away at the metal it really starts to put pits in the metal! so i think i ruined a couple of injector's i left in the vinegar too long?

Wow, no kidding! Good information to know. The dollar store in town was out of plastic storage containers. :?
Does Vinegar work ok as a degreaser too? Or will I need two bins, one for chem dip and another for rust removal? :D

no it's best to have the parts degrease prior other wise the vinegar can't penetrate the rust but it will cut through a little bit i guess?

I believe clbanman is exactly right.
In chem 12 we did similar stuff. Substances will always tend to neutralize. so like what clbanman said about PH; something very basic like chlorine will not work as a degreaser but it's excellent at eating away flesh if left long enough. That's why your hands feel slippery when they have bleach on them, it's actually killing the top layers of your skin and the skin just falls off.
Add a current to the idea with low PH substances and that's how you get plating. You reverse corrosion in a sense. Corrosion is exothermic I believe. So, add energy (electricity) and there you go.
High PH(greater than 7.0) is basic, low PH (less than 7.0) is acidic i think...
I dunno it's been ... 8 months and i hated my teacher. Wiki is always a good choice :P
Better than me, that's for sure. I just like to think I know a little about at least something :roll: .
All of which I've said is in very basic layman's terms of course.
(PH is a logarithmic scale of how much (concentration) either h+ (acidic) or OH- (basic) is present)
