Does anyone know of any wiper fluid that is easier on wax or windshield coatings/treatments by chance? I hear waxing the windshield is kind of pointless because the wipers and it's wiper fluid just wash it away in a few days anyways. If this is true, are there any known fluids that are wax or windshield treatment friendly?
 
I don't think it's pointless to wax the windshield, but I think that sealants play better in that application. Alternatively you could use a glass coating which would be more durable than a wax or sealant. There are also wiper fluids and additives that contain water-breading ingredients.
 
I would have to think the Rain-X wiper fluid would be a good option. Even if it does lead to removal of the glass wax/treatment prematurely, it will still have decent water shedding all on its own.
 
Sealant is definitely the better route for glass. I use CG Jetseal and in our somewhat rainy climate of north Alabama, it has lasted 5 months so far and the water still runs away flawlessly.

I use the Rain-x fluid in my vehicles.

I would go the coating route -- far superior than waxes and sealants. I use Prestone in my washer fluid. Doesn't alter the beading and sheeting properties of my windshield -- not in 3 years.
 
I would be careful with the Rainex washer fluid. In some vehicles, like my MK6 GTI, the chemicals in Rainex washer fluid will gum up the sensor in the reservoir and make the "empty fluid" light come on until the the tank can be drained and the sensor cleaned/replaced.

I've never been a fan of waxes or sealants on the windshield. Coatings might be different, but I found anything on the glass to cause streaking or even keep the wipers from completely cleaning the glass when conditions were misty/foggy.
 
I have heard that the Rainx brand fluid is known to gum up the sensors. I use the regular blue stuff from Advanced Auto, can't remember who it is made by. Anyways, April 2016 I tried Pinnacle Black Label Glass coating, it was on still March 2017. Still beaded, but was weak. I never had any issues with streaking, or wiper performance.
 
Ok so what about the waxes though? If there are alcohols in the washer fluid, wont that strip the wax on the car? I ask because this car has headlight washers and they spray the fluid all over the car when you hit the windshield wipers. Does common wiper solvent strip wax?

It's not going to strip waxes or sealants on it's own. Besides the majority of the time they are used while raining and even when dry, the wash fluid is going to evaporate and move off the vehicle rather quickly.
 
I'd try the Sonax Clear View Washer Fluid. You mix it up with distilled water, and to the best of my knowledge it doesn't contain alcohol or harsh solvents.

I would never use a wax on the windshield. Wax is pretty much passé anyway, because heat and the friction of the wipers will definitely make it go away over a short period of time. you just keep the windshield clear with Windex or something like that, or put a coating on it. I do believe using a polish on the car is a good idea , only to completely clean the glass before you attempt to put something on it.
 
Nexzett Kristall Klar Windshield Washer Fluid Concentrate 250 ml.

I switch over to this in the Summer months. Really does a number on the bugs. In fact ready to do my first batch for the season. I find it easier to fill the washer container first with water, then add the concentrate. I tried pre mixing gallon jugs, but when you go to fill up the container on the vehicle, it foams up too much. Just be sure to switch back before freezing temps again!

A tip right from Nextzett- use tap water to mix. Distilled water will make it foam.
 
I live in Southern California so there's not much of a need for washer fluid. I can't remember ever using my washers... But it sure pisses me off when the car in front of me uses there's and the overspray blankets my clean truck.
