Okay, I'm a fanatic with my vehicles and I really dislike water spots and related crud on my windshields. The new Ram was one of the worst in this regard when I got it, having set for sometime before coming to live at our house due to an order snafu.

Over the last several years I have tried about everything to remove this residue that was obviously nondestructive. I tried all the sure-fire commercial products and everyone's favorite elixir or solvent. No go. I checked with several on-line forums notorious for finicky car owners and all I got in those instances were things that seemed risky and/or no one had tried first-hand, or in one or two cases things that after being suggested on-line someone had tried and ruined their windshields--no joke, some will do anything they read.

Now, I'm sure there are probably easier ways than mine, but it works and is completely safe-just LOTS of work. I've done it on several new vehicles. And, fortunately, though getting the crud off is tough, keeping it off isn't.

In looking through my accumulation of vehicle maintenance goop one day, I spotted a bottle of Maguiar's #17 Clear Plastic Cleaner I use on motorcycle windscreens. It smells and looks like a watery, fine paint polish. So, I contacted Maguiar tech support and not only soon got the go-ahead to use it, but instructions, as well (good products and good service, imho).

The instructions included polishing every square inch for at least 30-seconds. This may not sound like much until you start doing it. With time, it is truly amazing when one finally sees truly bare, clean glass, maybe for the first time! The look is truly amazing (ok, too many "truly's"--sorry). When clean one can even feel and hear the difference when wiping the glass. For those nutty enough, savant enough, persistent enough, and/or masochistic enough to do this (or all of the above) I suggest doing no more than 1/4th or 1/3 strips of the windshield at a time. It is slow going and my arms (wimp that I am) feel like they are about to fall off each time I tackle the job.

Keeping it scum free? Simple, a nylon covered bug-sponge with Ivory hand soap, used often. When really clean the water sheets off about like with Rain-X (no, that doesn't work either).

Now, cjrmdc: you have another example of my "weird dislikes."

All the best.

 

hi was reading your post, i bought my 05 with the spots on all the glass, the best you can buy and works and as easy as windexing your windows,it is a product called bio clean, specially made for removing spots, acid rain, orfrom using poor water to wash your vehicle. company located in california
1800-341-5417. i was able to get a bottle through safelite auto glass this stuff is awesome and that is what they use, and it will not make your arm turn into jello from rubbing so much. i tried another product called rhodite works good but way to much work and required a small wheel and small area to be done at a time, also was $80 bio clean $15 try it truely amazing how it makes your glass look you will be showing everyone, also works awesome for polishing alum,chrome and fiberglass. if i new it would make it to you i would send you some out of my bottle so you can try it before buying !
i work for a very large water purification company for the united states, if you really like to baby your vehicles a cation/ anion tank setup for your garden hose is the best way to go,and you can get this from a water purification co. in your area this is pretty much a car wash setup, and not one of those mr clean car wash which is horrible. these tanks are what car lot washers use to spray down the new cars in the lot because it dries spot free. cation anion removes the chemicals which your city puts in water for bacterial reasons, which leaves spots and makes your wax jobs last a couple of weeks. i live in a very hot humid climate in louisiana, i usually wash my cars in the middle of the day with 95 to 100 degree heat with blazing sun and i never get spots! any questions drop an email
or if you would like me to send some of the bio clean let me know! thanks

Hey, many thanks. I'll try it.

Btw, I'm in north Louisiana, Ruston specifically. My gray Vette tag is "HI YAUX" (silver). Where are you?
