Do you buy windshield washer fluid or so you just put water in the container? I always used to just use water as it got the job done well enough, but last years I decided to test out some fluid because it was on sale and very cheap, it was a great decision, the added little bit of foam that it does really does help clean the windshield. Do you use it or some home-made solution?
I buy the windshield washer fluid only because I can get it for only $1 or $2 at the most. That's not exactly breaking you wallet. Besides I really don't know of a good alternative and I don't want to just use water and soap.
