Removing silicone caulking

Start by cutting off as much of the old silicone caulking as you can. Then make a thick paste with ordinary flour and water. Don't use whole wheat flower, we need the good old fashioned sticky stuff. Take this dough-like putty and rub it over the bit of silicone that is still forming a film on the tile or tub. This dough will roll the silicone up into itself and then you can rinse off the dough -- leaving a clean surface ready for new caulking.
