get the strongest,thickest, paperclip that will fit
throught the white hole, then take your nail clipers and bend the very end of it back around kinda like a fishing hook...!! when you stick it
through the hole the bent end graps the white part from underneeth and just lightly pull moving it from one side to the other, or just pop it off with your new tool..!!!
Works great for me and haven't ruined one white end cap yet ...!!!
