I have been using this for about 3 years now; first on my Audi Q3 and now on an Audi sedan. It cleans your windshield better than anything else I have ever used; and as the writeup on the product says: no buildup! I live on Vancouver Island and we get more than our fair share of rain, but also snow. This product will keep your windshield clean and streak free as long as used correctly.
