The kitten's eye may have been scratched, and then if bacteria got inside it could have become infected. You can get terramycin ointment for his eyes from the vet which will heal whatever has caused it. Just give your vet a call.
In the meantime, continue to gently wipe away the pus or mucus with a warm, damp cloth. Keeping the eye opened so that pus does not build up and cause blindness is very important. This will not heal any infection in the eye though. Only an antibiotic eye ointment such as terramycin will do that.
