Hello I have a two pill box that needs cleaning inside what would you use to get the board clean it,s been sitting for a long time and a lot of dust and dirt has gotten inside from top where the fan is. I won,t say who built this box because a lot of people got ripped off by him but I guess I was one of the lucky ones and I know folks will say it,s junk but I had a lot of good talk time with it and it worked well. thanks in advance cisco
