Assuming you do not have the cartridge puller,you can use a pair of channelock pliers.You will probably pull the center of the cartridge out ,if this happenstake a straight blade screwdriver that has a tip that will fit inside the outer portion of the cartridge and the sides of the screwdriver wont .Next gently tap the driver in the cartridge and turn and lift up.this works for me .good luck.
