I just got new BOSH wipers for my car. Its been raining real hard here Brooklyn and when i turn them on they make a bumping sound while wiping the windows and do it in streaks. On the way up they make this skipping bumping sound on the way down its good. They work fine but are very annoying. Do I need to oil them up with something or what do I do? Thanks, David.

 

maybe your glass is too sticky. try polishing the outside of your windshield. you can use stuff made specifically for glass like raindance or whatnot, or just use regular polish that you polish your paint with. either way it'll make your glass more slippery.

I noticed this on my Escort when I changed blades too ... I got so annyoed I bought another pair and it went away.

The way I see it, it could either be the wiper rubber material or improper installation of the wiper blade.

 

Every car I've ever owned made that annoying wiper judder across the windscreen. Rain-X helps usually.

 

It sounds like the windshield has a buildup of film on it. I've had good success with Bon Ami kitchen cleanser. It's like Comet powered cleaner, but is not nearly as abrasive and it won't scratch the glass.

 

I just put a pair of PIAA Silicone blades on my car yesterday and after a few drives in the rain I'm pretty impressed. They're more expensive than blade refills but they seemm to work very well and they're available in black or a carbon fiber style.

 

I'm a real stickler for super clean windows, and I mean all my windows. I clean the outside of my front wind with toluene once a year. Toluene is a dangerous chemical, but nothing cleans glass like toluene. Then with the glass super clean, I apply some rain x. To be honest, I haven't owned a car that didn't have rain x on it for years now, so I can't even really compare rainx to non-rain x now. I also, only use Bosch wiper blades on all my cars, and have NEVER EVER had a problem with them. I've tried everything from the silicone PIAA ones, to the teflon ones, and I always go back to the Bosch, because no one makes a wiper that does all the things wipers are supposed to do, as well, all together. They wipe as clean, are quiet, don't streak, and last easily more than a year with some refreshing every now and then (cleaning off the actual wiping part, with 100% ethyl alcohol, you'd be surprised how much gunk comes off when you do this).

 

I'm not real big on super-clean windows myself. Unless something extraordinary comes up I do them when I wash the car and I sure don't go the toluene route as I like my DNA just the way it is.

 

Rain-X it should help alot........it did mine

 

rain-x has to be one of the coolest things in the world!!
i jus changed my wiper blades last night too, sum aeroadvantage things, forgot the company..gotta put sum rain-x now after i wash it 2nite

 

Toluene doesn't affect DNA, it is not a carcinogen. It was believed to be decades ago, but research has proven it to be not a carcinogen. It is however harmful if used in an enclosed environment without propoer ventilation. But used outdoors, on a small cloth, it is not harmful in any way. Prolonged exposure through inhalation has been shown to cause kidney problems.

I find that getting the window ABSOLUTELY clean, then "sealing" it with a product like Rain X helps to keep it clean. All I really need to do to keep it clean for a year, is wash it like I would wash the body of the car.

 

What does RainX actually do exactly?

 

I don't think I'm that **** about my windows , hehe, j/k but I do like 'em clean, and I do agree that by far Bosch has the best wipers, the fist time I put them in even my friend who is really into cars was impressed, quiet and removes everything so nicely. unfortunatly living in New England, they only last 1/2 a year, but I might try cleaning them w/ alcohol, maybe that will prolong them.

also, where do I get this toluene that you talk about? I've never heard of it, but I'll give it a try

 

Toluene is a pretty widely available organic solvent. I'd think you could get some at a hardware store or at least a chemical supply house. If you use it be careful. It's very flamable, it will dissolve some plastics, and it will cause a chemical burn if it is in contact with your skin for very long. And make sure the area is well ventilated - prolonged inhalation is not good for your brain.

There are some other less onerous solvents that might do as well. acetone and isopropyl alcohol come to mind , but they may not do as thorough a job as toluene. Your call.

[edit]100% ethanol is actually kind of expensive. 95% is not and will do just as well in this application. The other 5% will just be water.[/edit]
