Disabling the Firewire Port

Okay, so long story short, I got some Axe Bodywash got stuck in my Firewire port. This is causing electricity to "boil" the shampoo in the firewire port, causing smoke and a horrendous smell to come out of the port. It's already completely useless now, but I keep getting notifications saying that my Firewire Port has been disabled. Now, it's turning off and on again because I keep getting these notifications. How can I permentantly disable the function of the port for safety purposes and since it's draining battery at a much faster, noticable rate?
