If you want to know what’s in your water your local water board will supply you with a full list of the dissolved salts and minerals and concentrations.

Volvo washer fluid is mainly Isopropyl alcohol it doesn't leave deposits. The water you use may of course but it doesn't in my part of the country . blocked jets just don't happen with volvos with the water we use down here .
