The gases in hydrogen peroxide are oxygen and hydrogen.
Quote from Wiki:"A peroxide is a compound containing an oxygen-oxygen single bond. The simplest stable peroxide is hydrogen peroxide."
It won't hurt the eggs. It's ok, if the chicks breathe it, but until they pip into the air cell, they aren't breathing air, anyway.
I've had eggs get broken in nests many times. Leaving it makes for a foul, stinky, bacteria laden mess, and a high likelihood of contamination of the remaining eggs. I've washed them off, with soap and water, sometimes repeatedly during one incubation, and had the remaining eggs hatch just fine.
Rubbing a dry egg with anything is more likely to force bacteria into the pores than rinsing it off.
Whether you clean the eggs or not, as long as you clean the nest and replace the bedding, and if there's any wet stuff on the eggs, blot it off with a paper towel, or rinse it off, and they'll be fine.
I wouldn't use saline. Salt attracts water, if you leave a salt residue on the egg, it can potentially draw moisture from the egg. And, it could be irritating to the hens underside, if she's plucked feathers off her belly, as many do. You needn't use sterile anything, the underside of a hen is not a sterile environment.
