My ex girlfriend did that to my truck once.

What a royal pain in the arse. Good luck with getting it all out though i know it ended up costing me lot's of cash because by the time she told me it'd been 4-5 days.

The worst thing i ever had happen to me was when they tried changing the anti-freeze to a new type and it was a bluish color, yep, almost identical to wiper fluid. Dumb arse mechanic put it in my wiper fluid tank and when i hit my wipers/spray that night i couldn't see out the windshield.

Picture me sitting behind the wheel of a 70,000 plus loaded semi truck and not being able to see worth a dang and running 65mph.

Luckily i got it to the shoulder and stopped but what a pain to clean off. Needless to say we stopped useing that type of anti-freeze and mech got a good reaming from me and the boss.
