Vinegar for water spots

[lakejumper]

I frequently boat in lakes that have high alkalinity. When I use vinegar in a spray bottle should I use it in full strength or dilute it? What ratio is best?

Thanks,

For the windshield glass I am guessing?

2) Vinegar and Water (homemade)
Mix one gallon of water with one cup of vinegar. Rub spots with a soft cloth. A few applications may be required before spots are removed. Note that after this use your wax will most likely be gone. Don't forget to re-wax.
