Are you sure the film you are referring to is not condensation on the windshield due to the dew? Even in rains the humid climate outside can cause such condensation on the windshield for a short while, this usually goes off if you are driving at higher speeds say 20-30 kmph.

Kitchen glass cleaner like Prill or Vim and or car wash in the reservoir, has worked for me.

Yup, its not condensation, its clearly old staining that becomes visible with water on the windscreen.

Kitchen glass cleaners haven't helped, neither the car wash in the reservoir.

Infact I even scrubbed the windscreen using a sponge with just the concentrates.

The active ingredient in all windshield washers is pure synthetic edible vinegar or diluted acetic acid that is 8% by strength mixed in distilled water. The one used in the kitchen for cooking which does not leave a residue on drying.. Use one tablespoon for 1 liter of filtered water. Do not use acetone or other chemicals as it will kill rubber parts and seals. If you constantly travel behind trucks and buses with diesel soot/oil mix accumulating on your windshield then 2 tablespoons of vinegar. If you have Teepol cleaner with you then reduce the synthetic vinegar by 1/2.

I have seen other posts related to this, but I really haven't found a post that talks about what can be done for old oil/road films that make the windscreen quite cloudy and spotty when it rains....

The issue I am facing is purely when it rains or early in the morning when the dew needs to be wiped off the windscreen. Wiper blades are new & smooth on the surface, but there is either a really old coat of road film/oil film/staining of the windscreen which makes it extremely hard to see through the glass at such times. Otherwise, when the sun is out and the wipers are not running, no issues what so ever.

What all have I tried?
- Toothpaste scrub
- Hot water scrub
- IPA cleaning
- Glass scrub with a deep cleaning glass liquid

Results
Pretty much, just marginal improvements for a while and then we are back to square one.

My question, what can be done for something like this other than replacing the windscreen (which is an expensive affair here even with windshield cover with the insurance)?

Please try scrubbing a handful of crushed leaves of Jatropha plant on the wind-screen. I have come across many cabbies who've confirmed they use it & that it helps.

It sounds weird I guess, but please try it. AFAIK the cabbies were quite serious. Its biological name is Jatropha Curcus You can google the images of how it looks. The plant used to be easily found along the highways, but since its used for bio-diesel, you may come across a grown plant only occasionally.

Looks like you have had water spots and they've etched the windshield as they're not going despite your efforts in cleaning. You can try getting the glass polished, if that doesn't work then you will have to change the glass.

I am using Prokleaner fluid in the reservoir but have noticed at night the windscreen becomes hazy. Will be emptying the reservoir and will be using plain water. Anyone had same issue ?

While the Maruti GA Screenwash which comes for ₹ 15.00 each is very good and I use it regularly. Apart from that I remember when I was a kid our driver used to rub the tobacco from a filterless cigarette on the wet glass of our Ambassador and it worked wonders. The wipers appeared to be more efficient in cleaning the glass and it substantially reduced water retention on the glass even during very heavy rains.

I am using this brand of washer fluid for the past 6 months. Adding about 15 ml for a tankful of water.

Although it cleans well it causes heavy staining wherever the left over fluid runs after use on the body panels. The fluid is blue color. This causes staining. This is terrible in case of light color cars, especially white!

The manufacturer recommends 100ml for a tankful of water. This is overkill and is aimed to finish the product faster.

Overall, not recommended . There are better options.

I am using Proklear and have no such issues, although I would highly recommend the ones available at Shell outlets (Sonax if I recall correctly). They are wonderful.

Ordered these concentrate tablets off aliexpress.com. One dollar for a pack of 6 and free shipping.

Dilute 1 tablet in 4 litres of water for your windscreen washer reservoir.

Works good. Really cheap and so far, no complaints!

Shell petrol bunks sell these windshield cleaners, and they're really good. Reading the fine print, I understand these are imported from Amsterdam

If you don't mind, could you post the picture of the ingredients side?

Can you please share the cost & dilution ratio ?

I use the Sonax (Best Windshield Washer Fluid?)one and am happy with that. However, it is bit expensive.

[Sebring]

Oh, I'm traveling. Shall do that very soon. But, It should be available online right. I use Sonax all the time, but this was too tempting. Dilution ration is 1:10. Pricing was under 300, so it's a good buy.
