Wipers

This is going to sound like a stupid question - but it's getting very frustrating. I have a 2002 Camry LE and my wiper blades are continuously streaking the windshield and doing a poor job clearing rain/snow in bad weather. I have replaced them several times with blades from different companies hoping that would solve the issue (one would figure it should) but they work for 1-2 weeks then the streaking comes back just as bad in the same locations on the windshield. I've tried cleaning the glass with different detergents, but it makes no difference. I do a lot of highway driving (300+ miles a week) and there are a lot of what seem to be very fine pits in the glass (you can't feel them as much as see them in bright sunlight) which I assume are from debris from the road. Could this be the issue? Any suggestions? It's getting to the point where it's hard to drive in bad weather at night.

1 - 2 weeks sounds too much. Even though the manufacturers recomenf to replace wipers every 6 month I think that all they want is to make money. Sometimes I take a wet rag, wipe my wiper realy good and it works for some time.

On an earlier version Camry, had a horrible time trying to find wiper inserts to fit from the dealer. Easy enough to transfer the metal ribs, but the replacements never seemed to fit as well as the original.
Wound up replacing the wiper arms with the inserts included.
Then they work well.
I've replaced the timing belt, half shaft axle and many other maintenance and repair items with no problems at all, yet nothing but problems changing the wiper inserts - however the replacement arms click into place in a matter of moments and work like new for around $50.
Would also suggest you clean the windshield very thoroughly.
I use an aerosol called Invisible Glass, with a cotton towel. A dilute solution of vinegar may also work well.
Pits in the windshield would abrade the new wipers sooner and reduce life but shouldn't cause streaking by themselves. Streaking indicates the wiper blades are not making proper contact or there is a film of some kind on the glass.

Try cleaning the blades with alcohol and a rag.

If you've changed the whole wiper blade assembly and the alcohol doesn't do it, try that stuff called RainX. Can't remember who makes it but it puts a thin coating on the glass and makes water bead up so it just runs off. Also I'm told snow won't stick to it. (I live in a desert). Let us know if you find a fix.

have heard RainX can cause problems later on with streaking, and is difficult to remove once applied.

I replace the entire arm assembly, not just the rubber ribbing. It's been pretty frustrating. I've cleaned the windshield pretty thoroughly, though haven't tried RainX or other commercial application (pretty much just glass cleaner and water/vinegar combos). I've had a million problems with this car so I guess I'll chalk this one up as another.

It's possible that what you're feeling on the windshield aren't pits but bumps. Some time before I owned my car, it was parked somewhere that covered it with tiny specks of something that stuck to my paint and glass. The effect was - as best as I can describe it - a fine glitter effect when I was driving into the sun. The paint will need a clay job, and I haven't gotten around to that yet. Butt a razorblade on the windows made a world of difference (and took off a lot of "stuff" even after the window had just been washed). Try that - if it doesn't work it was cheap anyway (although these days it might be hard to buy plain old razor blades!)
