Setting blank text in c# combo box

Question

So I am using a combo box that the user is only allowed to choose a few options. I am working on user validation right now. When you start the program the there is no text in the combo box. I want to be able to reset the combo box back to that default and make it blank when ever I need to. I have been trying things such as comboBox1.Text = ""; and that was a no go. I even tried doing comboBox1.Items.Clear(); Then re adding all the items back in again. Re adding the items wouldn't be an issue except one of the combo boxes is very lengthy.

Is there a way to make a combo box returns to its default of being blank?
