There's no moss killer available where I live (Northern Calif) so I'm using a bow rake and raking it off each weekend. Comes up easy. Also aerated the lawn to make sure water goes where it needs to, and shortened watering to 2 min 3 times a week. We have clay soil.
You can try vinegar but be careful not to get it on any other vegetation as it will kill that as well. I sprayed it full strenght and it killed the moss and some grass. Those areas are still brown after several weeks. I also found a product at wal-mart in the garden section that worked very well in just killing the moss. I don't recall the name but it came in a dark green bag and had moss killer on the outside. It cost about 10 bucks. Some people have told me lime will work but it has'nt for me.
