Windows, I can't get them clean!

[lj993]

This seems like such a simple matter but it is driving me crazy. It doesn't seem to depend the car or the window, I just can' t seem to get them spotless clean. They typically look great right after a wash, but the next day they show smears and streaks. I have used various cleaners, window specific cleaners, plain water, different types of towel, micro fiber and conventional. Nothing seems to help. Any secrets for getting your windows sparkling clean?

Thanks, Phil

You probably have a thin film of contaminates and needs a through cleaning. I find that Griot's Glass Polish works great as a prep. Do an IPA wipe down and apply a glass coating and you should have clean and clear glass after a wash every time.

You need a dedicated set of microfiber towels just for glass. If you're using a towel that has ever had a polish/wax/sealant on it, then it's a losing battle.

Glass needs to be polished to get rid of any road grime, waxes or whatever is on the glass that makes it streak.

Exactly.

All excellent advice.

Is your problem with inside or outside glass?

In my experience, inside glass needs very clean, and I mean VERY clean, microfiber in order to avoid what you describe. I have dedicated 400GSM waffle-weave that never do anything but clean glass and they all get very special treatment when washing to avoid any chance of cross-contamination.

If you are wiping wax overspray off of exterior glass, use your wax buffing MF for this and then after you're sure most of it is removed you can use your dedicated glass towels. Keep any wax or sealant away from your glass towels.

There are many very fine glass cleaners out there so as long as you are using one of those it should not be an issue. Stoner Invisible Glass is a good place to start but like I said, there are many very fine glass cleaners out there.

One of the best tips I learned is from Mike.
Is cover your windshield so you don’t get any splatter on it!
Like most has said using dedicated MF towels. I like Stoner glass cleaner
Personal. Polish with a 3” I use Griots with a Boss pad with Griots glass polish then I use Glassparency

I polish my windshield last.

Thank you for all of the great ideas. The inside of the windows is what is giving me fits. I will try dedictated window cleaning towels. Thank you. Phil

I agree with that a good glass mf towel is a important tool to get the windows clean. The no nap glass mf towels is those I get the best results with. The ones I use is not sold on AGO. But will link to some that I think is like those I have. It's also important to have a few at hand when cleaning glass. The first towel you use is to clean the glass with and the second towel is to wipe off any residue. And the second towel is going to be the first towel on the next window I clean and new towel to the second towel and so on when you going forward. I also wash the glass towels separate from other mf towels. The Sonax towel is a bit pricey but is that one that is most simualar to the ones I uses.

This GG PFM glass towels seems interesting too. With a little different technique from what I use. That you start with the longer nap side and finish off with the no nap side. Think this one can be a great glass cleaning towel.

Glass cleaners I use 2 different ones. One for the inside and one for the outside. The one I use on the outside is very strong and the downside is the smell gets to high for the use on inside glass. For the inside I like Sonax Glass Cleaner as it very clinging on the glass. And the overspray is minimal. I still like to spray directly to the glass mf towel to get the possible overspray out of the way. The Sonax has a little longer time till it evaporates too which is a good thing to the inside windows.

If you like WW this could be an option too. Designed to clean glass and with a different weave to get them effective to that.

If you still be haveing problems with streaking. I would look into a glass polish to get the deep cleaned. And then it would be no more problems.

And remember to work on as cool glass as possible to get the best results.

Polish Angel Diver spritzed on a Gyeon Silk Dryer Mitt is the easiest way I've found to clean interior glass, albeit a bit $$.

Gonna give it a try with less costly glass cleaner to see if it's the mitt or the cleaner that makes this easy and streak free.

Many people know that I am a big fan of the Zap Cloth and I would definitely have to recommend it for the interior glass. It cleans streak free without harsh chemicals. I usually do not use it on exterior glass because I don't like to grime it up that much. I will finish the exterior with the Zap Cloth after it has been cleaned with a good glass cleaner like Stoners Invisible Glass and a waffle weave glass towel.

I buy a couple of extras every now and then and give them to customers and friends. I even gave a couple to my boss and our company president. I still have my customers, my friends, and my job so I guess they work.

Interior glass can be affected by quite a few things. Organisms living in your A/C ducts could cause problems, too. It could be your vinyl, cloth, leather, etc. leaching vapors, it could be your own body perspiration causing humidity to increase. Once it clings it is nasty to remove.

I have been using Magic Eraser on the interior windshield with a lot of success, followed by a quality waffle weave with glass cleaner (I use Sprayway), then a dry wipe with a second waffle weave. But when I find streaks, it's always on the windshield or back window, and it's because getting to those is not easy. I'm a big guy, which makes it even tougher.

Larry at AMMONYC has a video about cleaning interior glass, and he shows a position for getting to interior windshield and rear glass that basically has you facing away from the glass and cleaning "backwards". I've been using that technique, and, although not perfect, has allowed me to do a much better job.

I also try to do my final wipes one way on the exterior and the opposite way on the interior, so I know which side if the glass isn't perfect.

Good luck to you.

It drove me crazy.... not anymore. This is what works for me, no more patches of haze or shoddy window cleanings.

No working in direct sunlight
Windows can not be very warm to the touch
Glass only white waffle weave cloths
First Stoner invisible Glass Cleaner with 1 white glass cloth
Next a wet glass cloth (ring it out/twist is first) followed by a 3rd dry one
Turn the cloths frequently... 1 time across then flip it
If exterior glass is stained heavily, etc., clay and use same compound/polish you used on paint.
