In: Chemistry

Answer 1

I don’t know the exact mechanism of jet dry, but a lot of drying products / hard water products include two things. First an acid to dissolve existing hard water build up. The second ingredient are molecules that bind to the hard water products and keep them from sticking to a surface. They might also include ingredients to speed evaporation.
