The way to fight inflammation is generally to leave a thing alone and stop irritating it. If some of the irritation is from harsh soaps or decreasers stripping your skin's lipid barrier, a moisturizer may help. It might even actually help loosen some of the gunk if it is something oil soluable like grease.
Hydrogen peroxide will probably produce more irritation. It's often not even recommended for disinfection these days because it causes damage to a wound along with disinfecting it.
Hearing loss can be a blessing...
