For those who use Barbicide, how often to you change it? The barber shops change it every few days or once a week. But since I'm the only one using it for my razors I don't change it that often. Before every shave I dunk the straight into it for a few seconds and then rinse it really well. I've been changing the Barbicide about every 6 to 8 weeks, but I'm thinking I could go longer.

What do you think?
