    Is it just me, or is the glass used in Tesla windshields extraordinarily difficult to clean without streaks? I've tried several different glass cleaners without success. Any successes out there?

    Pressure wash + Aquapel. Stays super clean (on the outside).

    I just use Windex and apply Rain-X. Haven't noticed a streak issue.

    I've been doing okay with my usual, Stoner Invisible Glass... of course, the glass must be cool or the Stoner glass cleaner will just make a horrible streaky mess.

    I use a two towel approach. I first use the glass cleaner to clean the glass as best I can. Then I use the second (cotton) towel to polish the glass until the towel smoothly travels over the glass. I had the same problem until I began using this approach.

    I make my own home brew: 30% white vinegar, 60% deionized water, 10% isopropyl alcohol, either 70% or 90%. 90 is better. I find that Windex streaks. But it does a better job on the bug guts. I also use the two towel approach. I use scrupulously clean micro fiber cloths that I only use on the car's glass. I dampen one and use the other to buff right away when doing the inside. On the outside, I spray first, wipe with a sacrificial cloth and then do like the inside. I often find that I need to do it two or more times to get it right. A total PIA. But I'm obsessed. I've tried all sorts of things and this simple brew seems to work as well as the pricey stuff and it costs pennies.

    One thing to remember on the inside is that the interior off-gasses for quite some time when the car is new. Especially when parked in the sun. Though the heat helps to off-gas more quickly so that you can be done with it. That lays a film of plastic vapor on the glass that is murder to remove. But over time, it goes away. Unfortunately, I always park in a garage, so I am still dealing with a little of it after 16 months or so. I have had this with every new car. Venting the pano, if you have it, and cracking the windows helps because it will vent out of the car, but not completely.

    ^^^Thanks for this. I also can't seem to get the glass right, and I was just thinking of picking up one of those spotless water filters that makes DI water because the water hardness here is really bad.

    I like the emphasis on the outside especially with a pressure washer.

    The two microfibre towel approach works the best for me.

    If you are using ONR optimum no rinse to clean the exterior of your car, it is the best glass cleaner that I have ever used. Dip MF towel in bucket contains solution of ONR. Wring out very well, wipe interior glass and dry with waffle weave MF towel. You can also wipe down and dry all of your interior surfaces including display screens.

    Damp rag of any type (plain water is all you need). Wipe glass down. Dry/buff with microfiber towel. Works like a charm on inside and outside of glass. I washed the windows and mirrors in my house this weekend that way and the wife was impressed with how great they looked. I just bought myself a new job I suppose.

    Thanks folks for all the replies. And to SPXMike, I have the spotless water system, which is absolutely fantastic on all parts of the car.....except the windshield!!

    I have really hard water here too. That's why I buy DeI water at the store. Yes, we are quickly wiping it off, so it should not matter. But I do find that it makes a big difference in both cleanability and in final finish.

    This from an over the top obsessed guy. But I love the results!

    Water from the sink and a microfiber towel works pretty well. No streaks, simple stuff :)

    I think the windshield itself is some kind of construction unlike all previous car windshields. Hazy streaks are impossible to remove.

    I have 2 other vehicles and have owned 20 cars over the years. The problem with cleaning this windshield is tied to the construction materials

    No it's just like other windshields to clean.
    +1 to Stoner
    +1 to the 2 microfiber method

    I've owned many, many cars and this windshield is not like any other to clean. All of the above are good suggestions, but it is really strange that this windshield just can't be washed and STAY nice more than about 24 hours. Maybe it gets better with time (7 months here). But I still love the car:)
