They are designed to clean water off glass. I've never lived in a dessert area so I may be wrong, but I expect they're not great for cleaning large amounts of dry dust and dirt off at least without using huge amounts of water.

I'd adapt it, of course. Not literal store bought wipers.

Some kind of brush is probably what you need for dust.
