A thick, good gage, coat hanger is a good way to go.
Each hook needs to be about 8 inches or more long. A 90 deg bend is not quite enough b/c it will bend back. Try about a 120 deg bend with the hook being about 1/2 inch long.
Pull very hard alternating left and right.
I made a loop at the other end of my 'tool' and place a screwdriver in each as a handle. Once the cluster starts to give, pull it slowly out.
