Can you make screen wash yourself?

Can you make homemade screen wash yourself?
You could, but it's a lot more effort and won't really save you much money unless you have these items in the house already. We wouldn't bother to make our own. After all, there are ingredients in washing up liquid that aren't suited to cleaning a windscreen, you don't know what damage you could cause. But if you're set on making your own screenwash, mix about 4.5 litres of water with a tablespoon of washing up liquid and half a cup of ammonia or vinegar (vodka would also work).
