What dbosman said. Learn to live with it.
Not only will fresh silicone not stick to old silicone it will also not bond well well to the glass that you thought you had cleaned off well. Silicone is almost impossible to to completely clean off glass. There is always a microscopic filling of the pores in the surface of the glass
