This user's talking about in accordance to "real life." I'd recommend you read the comment below this.

Demons, and Angels, in "real-life", possess not defined weaknesses. Salt, Holy Water, and iron - those are mythical-based presumptions. And exorcisms are an extension of the power of Jesus Christ, an invocation of his hallowed Name. Angels can only be harmed/killed by fellow brethren, and God.
