My sister has a 2016 kia soul she bought with 9,000 miles on it and the windshield appears to have had something put on it in the past and when its raining, almost daily, after the wipers go it leaves the windshield very hazy. It looks just like the first pic here, http://www.autogeekonline.net/forum...-windshield-i-cannot-get-off-please-help.html, I haven't really tried anything yet but after reading through that thread I was just going straight to polishing it since the hole car needs it. My question is can I use regular polish or do I need glass polish? I have the XMT polishes 1 thru 4 and some ceriglass. I was reading that the ceriglass is pretty intense so I was worried about using that.
 
Any car or windshield polish would work. But you're going to want to thoroughly clean the wipers or just get new ones.
 
Machine polish the windshield and only use a good quality glass cleaner (I love the Wolfgang one) and buy some new wipers. That should fix the problem not only short term but long term as well.

Good luck!

Try the least aggressive method first. If that doesn't do it then go more aggressive.

I had a similar case and it cleaned up with McKee's polish + white hybrid pad on a Flex 3401.

Ceriglass is for removing scratches in the glass. That doesn't seem to be your issue.
 
Is it safe to use the same pads on paint you're used on a windshield?


Any chance you'll get little bits of glass embedded in the pad?


Thanks
 
Possibly, but it could just simply be nasties sprayed up from the roads.

As has been mentioned, get the glass clean, and I think the best way would be through basically chemical means. Do not resort to 0000 Steel Wool, or Scotchbrite Green Pads!

First try the Plastic Baggie test with a thin Sandwich Bag placed over your hand and feel the Glass. Sure, you can clean it first with any Glass Cleaner you like.

99% of the time, Claying is usually in order, that the Glass will feel like Sandpaper.

Once past that step, you can try a wipe down with 91% IPA Alcohol, or the AG Pinnacle Glass Crème (Water Spot Remover) in a Bottle is superb at cleaning, and removing cruds.

Then repeat with a good glass cleaner, Stoner's or Sprayway in the can.

If the Blades are new, clean them gently, or if they are toast, buy a good pair, as I do believe you do get what you pay for. The cheapies don't last worth a darn. and usually chatter like hell shortly after installing.
 
I'd get new wipers first, totally eliminating that variable. Simply because they're relatively inexpensive. Then you can do testing before/after polishing.
 
Some big enemies of Glass. Spray washes, which usually are nothing but non-potable recycled very hard water, sprinkler systems, and trees.

If my previous methods don't work, then up the ante and buy yourself a small can of denatured alcohol. Be careful with it, carefully apply it to the glass only, and wear nitrile gloves, it is hard on skin.

Next step up from denatured alcohol would be acetone, but this stuff is deadly to human health, and can be very damaging to plastics and paint.

The other variable on glass, and is almost impossible to remove, is Silicone. And many wax and detailing products that may have been applied is a common ingredient.
 
My mother's Mazda has a nasty scratch in the glass where a bit of bare metal from a wiper rubbed against the glass. Looks really bad, but can't really feel it with your finger.


Was thinking I'd need to use a cutting pad with a compound like 105, but maybe even that won't do the trick. Scratch looks really bad and is right in front of the driver's face.

Yep, wiper blades, no matter who makes them, don't expect even a year from them, unless you own a garage queen that sits in a garage 90% of the time. The factory blades are likely garbage.

In some ways, I wouldn't call wiper blades inexpensive. Nobody seems to have simple re-fills anymore, you have to buy the entire assembly, and they ain't cheap! $20-$30 a pair is common, and many vehicles today of course have that rear wiper Arm and Blade.

Under intense sun and heat, like here in my neck of the woods, a desert setting, dust storms, and less than pristine clean roads, they take a beating. Drive down the highways, with a rain that comes once every 3 months, you'll have 3 months worth of crud being sprayed all over your vehicle, and the glass.

I can detail my daily driver with whatever cutting edge wax or sealant, and a week later there's films and haze on board where I'm almost needing to yank out the DA to remove.
