Oily Film On Windscreen

[Gyiman]

Hi All,

I have a oily film on my windscreen that I cant seem to get rid of. Any thoughts? I have tried different wash liquids through the windscreen washer as well as direct application, glass cleaner, etc. Nothing seems to work. My wiper blades don't appear to be bad, as they do clear off the water.

Any thoughts?

[heavyD]

Did you try changing the blades?

Any thoughts?

Wiper blades quality cannot be guarantee by just looking.

I also suggest you first change the blades like Big_D mentioned..

No I havent changed the blades. will try that next, thanks.

But what I did do was wash the windscreen & I also tried physically scrubbing it with a sponge, along with washing the blades. So i thought that would actually take the oil off?

Before you change the wiper blades, try this. Take a sponge or a clean bit of cloth, wet it with vinegar and run it along the rubber of the wiper blade. This should condition it back to reasonable condition (albeit temporally, but it's always worked for me). See if this makes any difference and you can rule out the wiper blades.

Also make sure this mist is on the outside of the windscreen not the inside (I know it sounds silly but you need to rule out the obvious first ).

I've seen this once before, many years ago on a friends Hiace. They replaced the windscreen with a used one from Delkanda and the new one started developing this oily mist outside the windscreen. It was almost as if some chemical was on the outside causing this problem. I'm not sure if they got it resolved but it was quite dangerous on rainy days. It was also definitely not the wiper blades.

I suggest if after what I've suggested with the wiper blades, if you're still having problems, take the car to a place that specialises in windscreen and explain the problem to them.

I also had the same problem. Windscreen get oily after driving for about 30 mins but it goes away as soon as i splash some water and turn on the wiper. I believe that it is caused by some chemical from the exhaust being deposited on the wiper blades. But once, one of my friends told me about something different scene. He has bought a new wiper blade which has some sort of oily thing on it which will get coated on the windscreen for better performance and stuff, but he said that it has been causing the same prob to him and he had to replace the wiper blade.

Vinegar huh? Now that's something to try out. I've always just wiped/washed them.

I actually picked it up from an Indian car show many years ago. It reconditions the rubber, and you'll be surprised with the results. I personally have to do this every time I come back to SL, because the wiper blades of my car never work properly due to not being used, though they are genuine Bosch (or maybe because they were purchased in Europe and unsuitable for SL conditions)! Works every time! as long as the blades themselves are not falling apart.

Another trick since I'm on the subject. If you ever find that your windows are not moving up and down properly (they stick or need more force to open or close), spray the rubber guides with silicone spray. It does wonders and reconditions the rubber and provides much needed lubrication. I've found this a lot more effective than the substance my local windscreen guys use (theirs lose their effect after a couple of days, silicone spray lasts a good year !). Again I have this problem because the windows don't get opened that often !

I thought vinegar is something we use in cooking.

Eevn I had the same issue and just to check if it was due to bad blades , the guy wiped out them with brake oil.It worked and changed the blades. Problem solved...easy as that.

Also pls not this happens due to some chemicals that sevice station people use to give them a shiny look but you hav eto pay a big price when it rains........

I just ask them not to apply any chemical but wipe it out with waste newpapers.... ( pls dont say " I thought we use newspapers to read news.

Hi

Few days ago I just tried with high pressure water (a domestic water pressure gun using for car wash) directed to windscreen. All oil marks and dusts went off completely. Now my car windscreen is very clean and good visibility in night & even rainy days

Isn't that a risky operation using brake oil? Getting it onto your paint work will seriously mess things up.

Sorry, not sure where you can buy it in SL. I bought mine off E-Bay. It is just a lubricating spray for rubber. I think rubber grease used for brake part lubrication would also work but it's not as easy to apply as a spray. Silicone spray also leaves no marks on paintwork or trim and excess can simply be wiped off safely.

Try vinegar, it smells a bit but its not as corrosive as brake oil
