What is the best way to clean out a coffee maker?
I recently bought a Coffee/expresso maker for my girlfriend from Goodwill for Christmas. It's super cool and professional looking but it's kinda dirty inside. Normally when I'd wanna clean something, I'd run like barsol or laquer-thinner through it because I love high powered solvents, but I also would prefer not to kill my girlfriend. Anyone know of anything I can run through a coffeemaker that isn't toxic but kills germs? They make coffee maker cleaner, but it doesn't seem like it'd kill germs.
I was thinking vinegar.
