dog with red eye

Hello, I have a 2 year old male lab pit mix, fr a couple his left eye has been running alot and has dark green/brown "eye bugers", we hav a vey dusty back yard where he likes to play with our other dog so we thought maybe he got dust in his eye, then we remembered we also use a squirt bottle o stop them with unnsessasary barking and it has always had a "listorine" smell to it bt I've washe with hot water and soap, when we squirted him I h him in the eye and I also seemed to start around this time. We got about a half cup of warm water and poured it on his eye to flush it out, and the next day I boiled some water and made a 1/4 teaspoon salt to 1 cup water solution, let it cool till just warm and flushed his eye out with about 3/4 or the cup and then sipped and rubbed his eye down with a soft washcloth covered in the warm solution, it imediately looked better and did for the next few hours, but his eye still runs and makes bugers, and today we noticed what looks like a cut on the inner corner of his eye that wasn't there when we flushed it, I don't know if the corner of his eye is just really swollen so it looks cut but it is not bleeding at all. This dog is my boy please help m fix him, I have very little money to take him to the vet so I am hoping for a home remedy or for you to say is ok and can heal on it's own. I am going to try to copy and paste some pictures in this message but I don't know if they will show up, if there s en email I can and them to so you can better help me diagnos the problem please let me know.
