Clean Pores

I have a few places in my face that are pits from large knots that I got a long time ago. Now they want to make blackheads. I read about oil cleansing treatment and decided to try it out. It calls for three parts castor oil, seven parts another oil (olive oil or grapeseed oil). I used warm water on a washcloth to open the pores and then put the oil on and rubbed it gently. Then I used the sonic cleaning thing with the oil on it. My pores and skin in general feel good and appear to be clean. I tried the sonic cleaning thing with facial soap and didn't notice any difference. I tried the OCT and again, it wasn't what I was trying for. Together, they work well for me.
