I've lost count of the number of products and techniques I've tried to try and get streak-free windows, especially the inside of my windscreen.

Has anyone found a product or technique that actually delivers? And if so, are you willing to share your secrets? biggrin

Autoglym car glass polish - don't use too much or it goes powdery - and use a clean cloth that hasn't been washed with fabric conditioner.

The streaks are build up of product either on the glass or on the microfibre you are using and oils from the aircon usually or other things like vaping or road grime.

I wash my windows the same inside as out, obviously a lot less water, basically squeeze the mitt out as much as I can. The shampoo will remove the products on the window and then dry them with a clean MF.

This won't work if you use a shampoo with additives such as wax but with a pure style shampoo it works well.

If I really have to I use Infinity wax glass cleaner on a dedicated glass cloth and that works well.

The problem with most glass cleaning techniques is that you tend to simply smear contamination around with the cleaning and polishing cloths.

Place a large towel across the dash to catch any drips and then use a pure shampoo and wash mitt (not soaking)just as you would on the outside. Squeegee across the screen with the blade at a slight angle to prevent lines and then carefully dry off the edges with a clean lint free cloth.

It's a pain but the only method I've found that leaves the screen smear and haze free.

Use a clean, dry multi-fibre cloth with no product on the windscreen first.

Remarkable what it grabs off the screen.

After that point, i use Autoglym Fast glass.

I think that's where the 'powderyness' of Autoglym's window polish works as it absorbs contamination. Just have to be carefull not to use too much or it gets everywhere - your towel tip would be useful when using it, at least until you get the amount right.

Lots of scrunched up paper towel, wet under tap and a squirt of washing up liquid. Wipe windscreen thoroughly with it and then dry with scrunched up dry paper towel. Never fails for me but don't be stingy with the paper towel.

I ran out of glass products a while back, and have since just been using Autoglym Rapid Detailer (just a quickdetailer on a microfibre cloth) - works fine for me, will continue to use it.

Washing-up liquid/white vinegar/water solution and....a chamois (yes I know, those old things). Never found anything better and microfibres are utterly rubbish at cleaning windows.
Then dry any residual water with an old cotton t-shirt

Vinegar and newspaper. What we used to use in basic training in the army for mirrors. Nothing worked better.

If you use normal liquid glass cleaner, then the best cloth to use with it is a waffle weave cloth. The ridges work really well in applying extra pressure to the screen and also gets rid of the smears.

But most of the time I use the blue Autoglym stuff. When you get the application right, you can smear a thin film of in on the windows and the powder residue means you can see where to wipe. If I'm using it, I always clean the interior windows before vacuuming the car.

I use panel prep as it evaporates off. Have also found the Screwfix no nonsense glass cleaner is cheap and good too.

There's another one they do: Clean and Repel and that too is a very good product.

IPA (isopropyl alchohol) on a microfibre cloth

About £7 for a litre on Amazon. Dissolves any oils and evaporates away.

This is what use. Sometimes takes a couple of goes if the windows are really bad.
