Rub the rust with a peeled potato dipped in baking soda or salt. Rub rusty tools with a soap-filled steel wool pad dipped in kerosene or turpentine.
“The element iron is the most abundant transition metal on Earth and has been used by mankind for over 5,000 years. Despite its strength, iron is prone to corrosion in the presence of water and oxygen.
Although iron and steel structures seem solid to the eye, water molecules are able to penetrate microscopic gaps in the metal. Rust causes the metal to expand, which can place great stress on the structure as a whole.
In general, corrosion is the deterioration of a metal by oxidation or other chemical action. Aluminum is one of the most commonly used metals on the planet, and it’s arguably the most famous for not rusting.
Copper is naturally brown and turns a shade of bright green as it corrodes. While some consider copper’s reaction to be tarnish rather than oxidation, the metal still undergoes a similar rusting process.
The alloys form a protective rust patina which reduces the corrosion rate with time. The iron or steel object is coated in a thin layer of zinc.
Gold never reacts with oxygen (one of the most active elements), which means it will not rust or tarnish. Gold tarnish is very thin and shows up as a darkening of reflecting surfaces”, states Corrosion Doctors.
Corrosion Doctors explains that “silver is a brilliant gray white metal that is quite soft and malleable. It is quite resistant to corrosion and does not oxidize easily, although it readily forms a surface tarnish of silver sulfide.
Due to these qualities (and its relative scarcity), it is often classified along with gold and platinum as a precious metal”. This allows the formation of a protective film of chromium oxide which acts as a shield against rust.

The part of the can that is in contact with the liquid appears like galvanized steel (crystalline surface or spangles sort of appearance), while the part that are not looks pretty shiny like the outside of the can. When I came back later, I emptied the water but noticed that the bottom rim of can have quite a bit of rusting.
After inspecting it closely, I found that there are spots of (concentrated) rust on the cylindrical wall of the can as well. There are also light patches of rust on the inside bottom of the can.
Well, that does sound like what you were describing, but galvanized steel is not fit for foodstuffs. Zinc is mildly toxic and ingesting it can make you ill.
I like feet wet's suggestion; that universally the inside of metal food cans are lined, by actually an epoxy that is sprayed on. Perhaps this makes sense: if your can was indeed galvanized, then the rational by the manufacturer was that the lining will keep the zinc separated and the food safe.
And BTW, why does the emptied and washed can smell “me tallish”? While zinc does have a metallic smell to it, iron oxide's is much stronger.
$\begingroup$Most modern steel cans for food are given a hermetic plastic coating on the interior. Depending on how hot you got the can when testing it you could have melted or vaporized the plastic coating, exposing the unprotected steel.
Interestingly, I actually did a related thread on it in another forum when my cutlery was unexpectedly (and seemingly, unexplained) attacked. Others reported similar experiences, with my experience starting with mango juice exposure to stainless steel steak knives left unwashed in a sink.
The surface phenomena that you see that looks like galvanizing is the organic acids in the fruit attacking the tin, which forms tin oxide and has a gray modeled appearance. The tin coating is only resistant to corrosion in the absence of oxygen; once you opened the can, the tin is able to oxidize and leave exposed steel, subsequently allowing rust to form.
They are durable, withstand weather extremities, are resistant to fire, mildew, and insects. Besides these attributes, tin roofs are affordable and easy to install.
This will necessitate a thorough cleaning of the roof to remove all dirt and any rust that may have set in. For quicker drying, you can wipe away residual water with a rag or old towel.
This will prevent dirt from being driven into the tin roofing material as you paint. Paint your roof every 3 years to prevent tin rust from developing.
Once it sets it forms an effective barrier on the roof against corrosion and rust. Like with painting, it is important that you clean your roof well before you apply the coating.
You can enjoy doing a color change to your roof if so desired to give it a new-look while extending its durability. The zinc forms a coating of several layers over the tin and effectively protects it from corrosion and rust.
It toughens the roof from extreme weather such as hail, snow, and excessive heat, all of which can facilitate rust. A galvanized tin roof does not require any other chemical treatments to prevent rust so it is cost-effective.
Once galvanized, there are no maintenance procedures necessary except for general cleaning as the need arises. A lyric from The B-52's hit song “Love Shack,” tin roof, rusted is interpreted by some to mean “pregnant,” usually with an unintended baby.
Tin roof rusted is one of the most famous lyrics from new wave rock band the B52’s 1989 song “Love Shack,” but it apparently came about by accident. Call me an asshole all you want, but if you sing out TIN ROOF, RUSTED” at the top of your lungs while Love Shack is on, I'll slap you hard.
Due to the popularity of The B-52’s Love Shack and the speculation surrounding the lyric, fans of the song often use tin roof, rusted on social media or in product names (e.g., Tin Roof Brewing Company’s Rusted IPA) simply as a reference to the track. Occasionally, a select few use the phrase to refer to pregnancy, though also usually in knowing allusion to the popular gloss of the lyric.
This is not meant to be a formal definition of tin roof, rusted like most terms we define on Dictionary.com, but is rather an informal word summary that hopefully touches upon the key aspects of the meaning and usage of tin roof, rusted that will help our users expand their word mastery.
