Sorry, just read Tabo's post, just to clarify, the small tubes from MB is NOT anti-freeze protection at all, they don't state that it is either. In the winter you need to use your OWN anti-freeze stuff, and MB sells this additive stuff. I don't really think the additive stuff does all that much, just use a "name brand" washer solvent, it may work better. The additive stuff smells an awful lot like dish soap to me........
