Hi guys!

Every time I wash my car I also clean the windows. I have a great window cleaning towel that I use on the windows, it is one of those lint free towels. I also use Windex. I've been having particular difficulty lately cleaning the inside of the windshield- after I clean it and I drive facing the sun, etc. I see this film on the inside that makes my windshield look extremely dirty even though I just cleaned it! What could it be that I'm doing wrong? Any tips on cleaning the inside of a windshield?

I use the same process for the inside and outside of my drivers side/passenger side windows- I do not have the same issue with those.

 

What I do is just use the lint free rag by itself and it won't leave any streaks

 

People have a tenancy to directly spray a product (such as a vinyl or plastic cleaner) onto the top surface of the dash to clean it. (Do NOT do this; spray the product onto a towel instead.) This causes some product to make its way onto the glass, which ends up affecting the opacity of the glass, and making it more difficult for glass cleaners to do their job.

Also off-gasses attach to the glass, esp. given its large surface area and exposure to direct sun.

Product wise I recommend Adam's Glass Cleaner.

Technique wise I recommend Larry Kosilla: http://www.ammonyc.com/detailing/car...ing-polishing/
(Skip to 11:55 for inside.)

 

here are some suggestions.
Adam's Glass Cleaneris great.

Auto Finesse Crystal Glass Cleaner

Uber Hi Tech Glass MF Towel

a trick we sometimes do is on a mf app pad you can use a pre cleaner polish to remove all the grime on the glass.

 

What makes the glass cleaners special, compared to a product like windex? I'll buy a window glass cleaner, but I don't want to spend money unnecessarily.

I may have gotten some of my vinyl cleaner on my window by accident through overspray. I'll have to be more careful.

I could really use a product that would clean off windshield grime. I am fairly meticulous about washing my car and keeping it clean, but windows tend to be my weak spot. It's really hard to get windows perfect.

 

I don't know. I do know I've gotten cleaner glass with Adam's than anything else I've used.


Fair enough. If you're not satisfied, Adam's has a 110% money back guarantee. (I'm not telling you how to spend your money; rather what has worked for me.)


Did you watch the entire video? I've used his regime and it works. (When it rains I often don't have to use the wipers because the water is quickly rolling off the glass!)

P.S.

Rain-X is for exterior use only. (They make a product for interior use but I have not used it.) Don't let Rain-X get onto your paint! (I cringed during a couple of Kosilla's videos as he's applying Rain-X over paint, and then setting the open bottle tilted on the cars.) I use large cotton balls to apply Rain-X, and I wear gloves while doing so.

 

I only use Stoner's invisible glass to clean my windows, inside and out. Amazing product, amazing results.

 

I've used rain-x on my windshield numerous times in numerous cars. It honestly works great!

Thanks for the suggestions, and I did watch the entire video. I really need to change my technique and I will be following what the video recommended the next time I wash my car. I have a bad habit of not folding the towel over and spraying directly on the windshield, and I think that both of these things are the reason why I have a film leftover that becomes apparent when driving towards the sun.

I'm going to give Adam's a try. I have yet to have a s2ki recommendation let me down Thanks for all the tips!

 

The ammonia in Windex is not good for cleaning glass. The reason for the annoying film on the inside windshield is due the plasticizers in the vinyl dash which outgas and deposit on the windshield. I use a good glass cleaner without ammonia (Invisible glass has no ammonia) and a special glass cleaning cloth which I buy from my detailing supplier. It is a very thin tight woven microfiber cloth which pulls the film away with 2 or 3 passes. I spray the cleaner on the towel rather than spraying it directly on the windshield.

 

The continuous off-gassing from the plastic & vinyl & etc. is the reason why the interior glass requires regular cleaning.

I presume a higher ambient temperature (e.g., summer time) would require more frequent interior glass cleaning than when it's lower.
