Problem with clearTimeout

I want to paralyze setTimeout with clearTimeout but there is no way. The code is as follows:

function limpiarModal(){
    $("#ventana-emergente").animate({top:"-350px"},1000);
    set=setTimeout(function(){$("#ventana-modal").css("visibility","hidden")}, 1000);
    $("body").removeClass("clase-modal-body");
    $("#ingresar-nav").css('cursor', 'pointer');
    clearTimeout(set);
}

The issue is that I want $("#ventana-modal) to be hidden after 1 second and with clearTimeout "clean" the accumulation of setTimeout .
