How can a roll of 1943 steel pennies that have oxidized over the years be cleaned?

Unfortunately, there isn't really anything that can be done to clean them. The coins are coated with zinc, which has its own oxidation problems, and combined with rusting steel underneath it makes a nice chemical mess. Anything you have at home will only make the situation worse, long term.
Zinc on steel proved to be unsatisfactory just within the first few months of use. It was so bad that copper coinage was resumed in 1944 in spite of a desperate need for that metal in making weapons.
In any case, unless the coins were in XF or AU condition to begin with, they'd only retail for 25-50¢ so you are not out a huge amount of money.

Among American pennies (cents, actually) only the famous wartime steel cents made in 1943 are magnetic. All other US cents are made of metals such as bronze or zinc that aren't attracted to a magnet. In 200 Canada changed the composition of its cents to copper-plated steel, so those coins are attracted to a magnet but earlier issues aren't British pennies have been issued in both bronze and copper-plated steel so depending on the year of issue they may or may not be attracted. In some years both compositions were used, which makes things a bit more confusing. Euro cents are all made of copper-plated steel so they too are attracted.
