What is this striation pattern/zebra streak on my glass?

[Regius]

First, these are not the conventional streaks due to poor glass cleaning practice. I am able to clean my glasses without issues and it's not that hard, the glass does its job which is letting me see through without water spots, dirt or other cleaning fluid residues. What I am observing here is an almost "baked-in" pattern that's only visible when I wipe my glass. Wiping with wet towel, be it water, soap water, glass cleaning spray, windex, chemical guys stuff, doesn't matter, whenever the glass is wet and a wiping motion has been applied to it, these vertical lines shows up. As soon as the fluid dries, they disappear (and the glass is done cleaned). So, are these some kind of coating from the factory? they are on both front and rear glasses.

Looks like rainx. Used it once never again, if it is it will go away in a few weeks.

Strange. Maybe some kind of environmental fallout/acid rain? The only things I found on my front and rear glass were the suction cup marks where it was handled at the assembly plant. But they have faded away with cleaning.

Thanks. I used the Clorox/CVS alcohol wipe, still there, used autozone aeosol ammonia free glass cleaner, still there. it's like permanently altered the chemistry of the glass. maybe it's meant to be there? UV filter?

Definitely not supposed to be there. That's not to say it's hurting things by being there though.

I had that on my last car. Thought it was just from wax bonding to the glass ? Never thought much of it. Could try glass polish.​

You should give it another shot. RainX works fantastic. The key is how you apply it.

-Clean the window with a good glass cleaner.
-Wipe on RainX, let it haze and then apply another coat or two.
-Here's the key. Let the RainX haze again and then hose the glass off w/water and wipe it dry with a chamois. The haze will disappear and you'll have perfectly clear glass that sheds water like crazy.

If you let it sit too long without spraying the glass and wiping it down, that's when you get that permanent haze.

I had somewhat of the same issue. My sprinkler system sometimes sprays on my truck glass. I got the streaks off by using polishing compound with a buffing pad on a electric drill. You may have to go over a few times.

Never heard of that before. I've been using Rain-X since it was invented decades ago and never had a problem with it. Works great. Back in the 1980s I had to travel from AZ to MS. A storm followed me the whole way. Heavy rain. Everyone I saw had their wipers going on high and sticking their heads forward to try to see out the perpetually streaking windshield. I literally did not need my wipers except when a semi passed and sent that light dirty spray on my windshield. The trick with Rain-X is to apply it then wipe a wet paper towel or cloth over it and then immediately dry with a cloth or paper towels.

The factory glass is dyed. It's colored glass.

There are patterns called "quench marks" which can appear in auto glass. These are patterns in tempered panes that will be present from new. But the shapes are mechanical in appearance, like a cookie cutter. Yours, they look like something involving a liquid, possibly foam.

"...both front and rear glasses." The front and rear side windows? Are the windshield and back glass affected?

Your truck is listed as a 2024. How long have you had this issue?

When the truck was purchased, were there any dealer add-ons involving the glass? Any treatments?

Have the windows been tinted?

What do you use to clean the glass? The liquid cleaning product?

What do you use to typically clean the truck? The soap?

When detailing the truck, what time of day do you often clean it? What's your process? Your tools?

Do you frequent self-serve (coins and wand) or automated car washes?

"...both front and rear glasses." The front and rear side windows? Are the windshield and back glass affected? A: by rear I do mean the rear door windows, not the rear facing cab glass. I don't pay much attention to the cab window so don't know, but these patterns are present on the windshield.

Your truck is listed as a 2024. How long have you had this issue? A: can't remember but I think I just recently noticed, but say they've been there for at least a year now. As said, you can't really see them unless you wipe it with a towel soaked in water of some kind of soapy water. These striations have a different hydrophobicity, it's like a strange ceramic coating job.

When the truck was purchased, were there any dealer add-ons involving the glass? Any treatments? A: not to my knowledge, this dealer don't bother to sell add-ons.

Have the windows been tinted? A: no.

What do you use to clean the glass? The liquid cleaning product? A: I don't particularly clean my glass separately from cleaning the whole car. I use chemical guy's bosywash & wax, or Maxi suds (one, not the purple II).



What do you use to typically clean the truck? The soap?

When detailing the truck, what time of day do you often clean it? What's your process? Your tools? A: after maxi suds and some quick wiping, the glass parts are just wiped dry, no special attention paid to scrubbing the glasses. That is, not until yesterday when I found out the chemical guys polishing compound, V38, and a lot of elbow grease (I'm sure a rotary polish gun is faster), the streaks do go away and the glass becomes homogenously hydrophilic.

Do you frequent self-serve (coins and wand) or automated car washes?

Glad to read no permanent damage was done.

"Carnauba is nature’s sunscreen. Extreme Bodywash & Wax is blended with natural carnauba wax and a synthetic wax to strengthen your vehicle's existing wax or sealant coat and restore the shine of a freshly waxed look."

IMO, ^ this caused those streaks. That and possibly the conditions the truck was cleaned under.

I used CG products for a bit a few years ago. And stopped. The CG soap I was using produced few suds, wasn't good at removing material. Their wax had a harsh chemical smell, was difficult to buff off. A sealer lost its properties after only a few washes. Their glass cleaner left more streaks than it cleaned.

CG has a confusing product line. Instead of one product for one purpose, they have multiple products often doing the same thing. They're constantly creating new products. Many of the items they do have don't perform well, don't last long.

My experiences with the CG line left me thinking there has to be something better out there. YMMV.

Specific to Extreme Body Wash and Wax and given the hot temperatures of the season, I'd expect it to act that way.

If you'd like to continue to use the CG product, some pointers, if not already doing:

- Use the product in the smallest concentration required to get the job done. Many times, less is better

- Never detail a hot truck. Don't clean it on a hot day in the Sun. Wash in the morning, in low light if possible, on a cool surface. If you've just driven the truck, pop the hood and let the engine cool for a bit. Wash the hood and front end last

- In using any product, rinse it off almost as soon as you use it. It doesn't have to be immediate, but don't let it linger. Definitely don't let it dry

- We can't wash an entire vehicle quickly, so continue to spritz the surface occasionally with water to keep it cool

I'd stop using a wash+wax product. Use one wash product, one paint sealer. I'd also study Gyeon's or CarPro's lines.

One product I routinely used on my vehicles is Gyeon's Bath. It's a soap which can be used as often as you like. It does not contain waxes or enhancers.

Gyeon also makes a nice wash mitt.

Virtually all of us wash outside. This time of year, I do so early in the morning. Better for the truck. More comfortable.

For applying a wax, paint sealer, cleaning the glass or protecting the vinyl, it's best to do that in a covered area, at room temperature. If you do not have a garage, early morning is best. Do not work in direct sunlight in the afternoon. Not good for the product. Not good for the truck.

I use a paint sealer. CarPro's Reload 2.0 works very well.

https://www.carpro-us.com/protectio...c53eI1Wj5wy3l9zJuOoEk8-4MfcgVhXGjCwycpmtJE1iN

It's simple to apply.

After washing and drying the truck, spritz a microfiber towel with Reload. You just want the towel damp to the touch. You don't want to soak it. Slow-walk that across the body panel, moving in a straight line. Work one body panel at a time. Reload will quickly flash over. You'll hardly notice it there.

After coating the truck, take another dry microfiber towel and buff it off. No residue. On initial application, the towel might feel quite rough on the surface. But when removing, the surface will have a nice feel, but not be overly slick. The sealer will last for a few months.

Wolfgang makes a great paint sealer. You can't go wrong using either Wolfgang's or CarPro's.

***DO NOT use soaps that have a wax or combination products with the sealers mentioned.*** Mixing things like that can produce poor results, build-up, haze, cloudiness, residues, etc.

For glass cleaning, simple cotton towels. I use these from target:

For a glass cleaner, Stoner's or Gyeon's works well.

CarPro Perl is good on vinyl and plastic.

Most of these products can be bought from their sites direct, or often through AutoGeek

Cleaning in-general, you want to practice separation. Microfibers used on wheel rims should not be used on the paint, and vice versa. Glass should have their own dedicated towels. As should vinyl. And they should all be washed separately, to prevent transfer of product or contaminants.

^ That seems a. bit much, but it is not. Get packs of towels in different colors, then use one color for one purpose. They can often be bought in six-packs. When you've reached the last one, wash those six.

Don't use laundry soap to clean your towels. Use a microfiber towel cleaner.

I use the products referenced on a regular basis. They work well. They're not the only ones that perform great. Other Members might have products they enjoy and list those here.
