You don't. The coins rusted once the zinc coating wore through.
In any case most 1943 cents are only worth a quarter or so in average condition. You'd be better off buying a better specimen, because trying to "fix" a corroded coin will only make things worse.

What is the corrosion on a penny?
Oxide
What effects does ammonia have on steel?
Ammonia reduces the rate of corrosion on steel.
Where is steel used in Rusting out how acids affect the rate of corrosion?
stain
Is Zinc as durable as stainless steel?
No steel is more durable. But zinc is usually used to coat steel or other metals because it is resistant to rusting or corrosion.
Which pollutant causes the greatest corrosion of steel structures?
Answer 1: oxygen and carbon in the air :-) Answer 2: Depends on what type of corrosion you are referring to. Rust and corrosion are typically used interchangeably. Rust is one type of corrosion. Corrosion is essentially the disintegration of a engineered material. Rust is a chemical reaction, but there are other chemical reactions that cause corrosion of steel (typically acids). Other types of corrosion include fretting, erosion, cavitation, and galvanic reactions. There are many methods to prevent corrosion. One of the most versatile of prevention solutions is electroless nickel plating. Electroless nickel resists all types of corrosion.
What was the purpose of the steel coating on a 1943 penny?
The coating is zinc, the core of the coin is steel. Zinc was used to reduce corrosion.
What is the corrosion on a penny?
Oxide
What material is better - stainless steel or carbon steel?
It depends on the applications. Stainless Steel is more corrosion resistant and more expensive. Carbon Steel is cheaper and less corrosion resistant.
What is pickling steel?
You probably meant pickled steel. Pickled steel is steel that has been washed in acid to remove surface corrosion before enter the next processing step in a factory (e.g. forging. stamping, rolling). The process of washing the steel in acid is called pickling. Once pickled the steel is rinsed in water to remove excess acid.

How fast does Steel rust?
Steel does not rust by normal corrosion agents.
What effects does ammonia have on steel?
Ammonia reduces the rate of corrosion on steel.
Which grade steel is best against corrosion?
Stainless reply: want to know steel grades other than stainless against corrosion
How long can a stainless steel material withstand corrosion?
Corrosion is a gradual destruction of metal by chemical reactions mixed with the environment. How long stainless steel can withstand corrosion depends on the thickness of the metal.
How many drops can you hold on a penny list one uncontrolled variable?
The penny's state of corrosion.
What is a 1944 penny made of steel worth?
The 1944 steel penny is worth between $75,000 and $110,000. This steel penny was minted by mistake and there were not a lot of them around.
