No don’t clean it yourself. Unless you are talking about the front and rear element.

I’ve had mine on a year now and no problems with dust. Try

  • Keep it out of dusty environment,
  • cover up with a buff, towel t-shirt etc
  • don’t swap lenses where there is lots of dust
  • clean the outside
  • when not in use, keep in a camera bag

Prevention is better than cure
