Whilst many – in fact most – windshield washers are designed to go into the washer fluid reservoir and be sprayed onto the screen, this is not the case with the first item on out list. If anyone is in a good place to make a more unique product it is certainly Rain-X however, who have been producing windshield liquids for over 40 years.
This product is quite like a wax, but for glass. So it is applied directly to the windshield where it is worked in with a clean sponge or microfiber towel – and a bit of elbow grease, supplied by you. Once in place it effectively forms a protective barrier, the most notable feature of which is that it causes water to “bead” on the windshield surface. This makes rainwater run off the windshield very easily, improving your vision in the rain.
