I approve, but as stated, that may have been slightly too far. I see it as basically the equivalent of someone punching you in the face, so you pull out a crowbar and whop them one across the nose. Justifiable, but a little too extreme too quickly. Personally, I probably would've just taken their clothes and dumped them in whatever dumpster happened to be handy, with a note on the dryer directing them to said dumpster.
Then if it happened again, I would have gone for the bleach.
You definitely did the right thing though.

If a person doesn't have the courage to stand up for themselves (and I mean so in a mature fashion, not in some backwards revenge scheme), then that's their own personal fault. Besides, you don't have to be a pushover when approaching the other person.
You can simply say, "I don't appreciate it when you do _____. Don't do it in the future please. How would you like it if that happened to you?"
Most of the time when you ask people a question it forces them into a different standpoint.
If they continue to be a jerk then by all means, don't just let them walk all over you.
But nothing excuses not taking the higher ground first. If people simply make knee jerk reactions to every situation because they are too afraid to simply confront the issue, then it will be an endless cycle that continues to escalate.
As a fellow person who has been taken advantage of, trust me, I know where you are coming from.
The vast majority of people who would pull something as described in the OP won't really care if you confront them. They'll make all the right noises, but as soon as they need a machine, they'll do it again. The only way to ensure they stop is to ensure there is a punishment that fits the act. The OP's response was a bit extreme, but not outside the bounds of reason.
Verbal confrontation does, in the vast majority of cases, nothing useful. Hell, there's a decent chance it would make you more of a target than anything else. The only way to make it stop is to respond.
