What's a good way to get rid of rain surface rust on tools left outside

Soak in Brulin's Unicide 256, uncut. Actually will migrate some of the metal back into metal.

Thanks for mucking up the entire post here, babbling Burnie; however, I was thinking about Charlie Brown at the time.

Googling, I find the MSDS over here:

I'll look up how ammonium chloride can remove rust since I always thought it CREATED rust!

Give us a few decades; we probably will.

Feh. AEU has manhandled it so far.

Dr. Hot"with kid gloves?"Salt

He does some nice stuff, including his wife I'd like to know what sources he uses to find out how things actually looked before people f'ed 'em up. It can't ALL be in his head. My grandson loves that show and American Pickers. I'd like to have either one of their jobs, seems like it be a lot of fun

Often if you turn off the water supply and put a bucket of water in the toilet bowl most of the water will go down the drain similar to when you flush it.

Are you insisting on a hyfen between the second and thrid words? It's pretty clear without it.

What the hell is "feh"?

I don't know who said that Coca Cola contains phosphoric acid, but that's not true. If it were, Coca Cola would taste acidic all of the time, but it doesn't. In fact, it's easy to remove the acidic "bite" from the taste of Coca Cola.

Coca Cola (and all carbonated soft drinks) contain an acid called "carbonic acid". They don't actually put carbonic acid in soft drinks. They only put CO2 into the soft drink and the CO2 dissolves in the soft drink and combines with H2O to form carbonic acid: CO2 + H2O = CH2O3, which is carbonic acid.

Carbonic acid is an inherently unstable molecule and breaks down to form CO2 and H2O fairly quickly, but as long as there's lots of CO2 dissolved in water, carbonic acid will form as quickly as it breaks down, and that water will remain acidic cuz of the carbonic acid in it.

It's the formation of carbonic acid from the CO2 dissolved in the water that gives Coca Cola (and all carbonated soft drinks, and beer, and all carbonated (aka: "sparkling") wines their acidic "bite" when you taste them). To prove that, just leave any carbonated soft drink sitting in a glass over night to let all the CO2 come out of it. Then when you taste it, it'll just taste sweet like sugar water and not have any "bite" in it's taste at all. If there were acid in the soft drink to begin with it, that acid wouldn't evaporate, and it would still taste acidic, like vinegar left out in a glass over night.

It's the carbonic acid you swallow breaking down to form CO2 (gas) and H2O in your stomach that makes you burp after drinking soft drinks, beer or sparkling wine.

I kinda doubt that the amount of carbonic acid in a soft drink like Coke would be sufficiently strong to dissolve rust, so I'd stick with phosphoric acid which does work.

HCl is just going to cause rust. I use muriatic to dissolve galvanizing (for welding), and all of the ferrous objects near the bottle end up getting very rusty.

Jon I have found that to be true also. Used muriatic acid in my shop to remove some alkali from an item and the fumes rusted all the tools nearby.. WW

Wrong.

When you start with a false statement, nothing that follows is worth reading.

Or once in a while, a stupid Brit.

If you tell me you are "Sat on your ass", I don't know whether you are an idle fellow or the owner of a donkey.

I meant funny/peculiar not funny/haha!

Bit here on the topic. Used as food/colas additive and as a rust remover. Apparently there are different sorts.

Another good reason not to drink Coca Cola.

Naval jelly and Coke are the same thing.

If you drop a penny into the liquid [remove any oil films] in about 30 seconds it's shiny like new.

I have no idea how much phosphorus there is in Coke, but phosphorus and phsphoric acid are not the same thing just like carbon and carbon dioxide are not the same thing. And, of course, a ml of water weighs very close to one gram, so in approximately 100 grams of Coca-Cola, there are 18 milligrams of phosphorus, or about eighteen one thousandths of one percent, which is a TRACE amount, hardly the primary ingredient.

No, the active ingredients in Coke are sugar and caffeine. If phosphoric acid was the active ingredient in Coke, people who like drinking Coke would enjoy drinking phosphoric acid toilet bowl cleaner diluted with water.

Think with your own head... that's why God saw fit to give you a head. Leave a glass of Coke and some phosphoric acid toilet bowl cleaner sitting over night and taste the Coke in the morning. I won't taste acidic at all. So, where did the phosphoric acid go to? The phosphoric acid toilet bowl cleaner will still taste the same and behave exactly the same in every respect as it did before.

The acidic "bite" in the taste of all soft drinks, beer, sparkling wines and soda water is due to carbonic acid. That acidity in the taste disappears as the CO2 dissipates from the beverage. That's why soft drinks go "flat" if left open too long.

Phosphoric acid toilet bowl cleaner doesn't get weaker if left out overnight.

Bullchit. Naval jelly contains significant amounts of phosphoric acid. Coke does not.

Primary? No, but it *IS* added to Coke (and Pepsi). IOW, you're wrong.

What a stupid statement. Phosphoric acid is put there for a reason. It enhances the flavor.

You must have been sleeping late that day, however.

You're *WRONG*.

'snopes.com: Coca-Cola Acids'

The 2 to 3 tenths of 1 percent phosphoric acid quoted in that Snopes web page is what's in the syrup, not in the soft drink.

Assuming a mix ratio of 5:1, one gallon of syrup will make 6 gallons of soft drink.

'How many glasses of soda does a 5 gallon bag in a box syrup yield if each glass is 16oz? - Yahoo! Answers'

That results in a concentration of phosphoric acid in the soft drink of about 5 one hundredths of one percent.

Coca Cola can hardly be used as a substitute for phosphoric acid because it supposedly "contains phosphoric acid".
