What do you guys use to clean your windshield? I have my car about 4 months and I can't get my windshield clean. I have these drip like marks that are making me crazy. I can't get rid of them. And when I use the washers or wipers I get these bad streaks. Not sure if there is some residue somewhere that is dripping. No matter how much I clean the windshield, it doesn't go away. I've used windex and some non streak glass cleaner I use in the house with microfibre cloths but it just doesn't make the glass clear.

Thanks

Clay bar the windshield and then add on a sealant.

^ That should do it.

^ This. Works amazingly well. In addition, Stoners Invisible Glass cleaner is available nearly everywhere and I have yet find a better product for normal cleanings.

Here are some links to my favorite products...

Best clay - use a clay mitt instead of actual clay, much better:

Here is the best sealant by far. The ease of use is nothing short of staggering. Will last about 3-4mos on paint, a few weeks on glass if you use your wipers. Amazing product and a bottle will last a year or more.

Finally - here is a link to Invisible Glass, although any retail store also has it:

Clay bar and polish it, either using a machine or by hand. But I don’t seal my front windshield. I’ve experienced clatter before.

Thanks all!

I've clayed and polished mine before and even used serium oxide on it last year to remove some scratches and pits but I have never thought to use a DA and polish on my windshield. What polish did you use? 3 or 4 stage?

Anyone who says use a DA to polish a windshield is leading you astray. First, you really need to use a rotary to get any noticeable difference when it comes to scratch removal or removing pitting. Second, it's a messy messy messy messy messy messy job that takes for-freaking-ever. The amount of mess and time it takes to do it right is no where near offsetting the cost to pay my $250 deductible and just have the windshield replaced with a brand new one. Bonus points, comprehensive covers this - not collision, so no increase in premiums no matter how much you do it.

Here is another good thread discussing some of the things to watch out for when performing the process. Basically, you have to get the glass very hot when removing the defects, but it's easy to get it so hot that you end up warping it and causing more problems:

Agree on this completely. I bought some serium and a rotary pad for my drill last year and went to work on the windshield one Saturday morning. Six hours later along with orange powdery dust/slury all over everything; I saw mediocre results. That shit will seriously dry out everything it touches. I'm a DIY guy all day long, but I will NEVER do this again. Good to know on the insurance windshield replacement!

I did both of these a while ago and need to do it again. It was real nice for a while. The wax on the outside is fire.

Not sure if mentioned above

But I like any good dedicated windshield cleaner spray or foam and use newspaper to apply.

I find it curious they dislike newspaper. You cruise down the highway at 75 mph getting peppered by dust...

I had a bad streaking problem on my 1992 325is after the combination of these 3 things:
silicone blades
silicone windshield treatment
1 dusty road that just stuck to everything until I finally cleaned the windshield with denatured alcohol and changed the blades back to factory.
If it ain't broke...

I took delivery Oct 5th. Wipers are OEM, no windshield treatment. The glass just sucked from day one.

I just use RainX from time to time.

I used to swear by that stuff but then I read on one of the forums that it wasn't good for the glass. After time it would cause a residue or something to build on the glass.

Yeah - I feel it has mixed results. Sometimes it works for folks and other times it doesn't.

I am absolutely ridiculous when it comes to my front windscreen. Drives my wife nuts because I will pull over to clean a smudge. I typically shoot some glass cleaner (the invisible glass I mentioned) over the window and do a wipe down nearly every morning before work if it isn't raining.

That being said - let me know if you have further questions - I've tried literally everything and nothing seems to beat regular quick wipe downs and periodic sealing or clay.

Also - when cleaning, always use a dedicated rag just for windows. Had a hard time figuring out why my window would always streak until one day I realized I was using a rag that I had used to remove wax once before.

I have also found that the microfiber waffle weave cloths work much better than the normal microfiber towels. The regular ones will sometimes leave little particles behind due to the static they create. Not so with the waffle weave ones.

This is the one I use:

I'm a nut when it comes to clean windshields, inside and out. I always carry windex and microfibre rags. My drivers Ed teacher Mr. Briganza told us the most important thing is to have a clean windshield. Can you imagine? I remember my drivers ed teacher's name from 40 years ago but I can't remember what I left my office to get...

It's frustrating. A new car usually has that nice fresh windshield and it makes me happy when I use the wipers and the windshield is crystal clear and streak free. It's one of the things I look forward to when changing vehicles. Not sure why this one has all these strange drip marks and streaks. I wish the camera would pick up what I'm talking about.

1) Don't use Windex. It's a terrible product. Not only does it leave horrible streaks and stains on your window, if you use it on tint - it will melt it.

2) Don't use normal microfiber cloths - especially on the inside. Use a waffle weave or at least a normal cotton washcloth. In a pinch, a used tshirt is also a good option.

Seriously give the clay bar or clay mitt a try - I think you will be amazed at the difference.

I'm going to order the clay mitt, waffle weave cloths and pick up some invisible glass. Thanks again.

I've been using RainX and tired of the clatter; I just can't seem to buff it enough to get it to stop. I'm ready to try the clay mitt and invisible glass... any suggestions how to safely strip the RainX off the windshield?

Ugh. Rain X - evil stuff.

The most sure fire (no pun intended) way to completely remove RainX is to use naptha. Regular Zippo-type lighter fluid is naptha based. So is Coleman (or similar) camp fuel. You can also use VM&P naptha...found at most home improvement and paint supplies stores.

Naptha eliminates any RainX that has even found its way into auto glass' microscopic 'pores'.

It's somewhat nasty stuff. If you want to try a more soft method, then most APC's will work with some decent scrubbing.

Another alternative is McKee's 37 High Performance Glass Restorer on a White 5 1/2" flat foam pad with a Porter Cable 7424 dual action polisher on speed 4.
