My windscreen is filthy on the inside. It's cloudy, has fingerprint smudges, and suction cup marks from the GPS holder.
I've used Windex, metho, vinegar, eye glasses cleaner and cloth, commercial brand automotive window cleaners/clothes and nothing works right. Smudges still appear.
Does anyone have some advice for me on what works a treat for them? Something to make the windscreen crystal clear would be fantastic.
Thanks heaps.

I go over mine with the chamois about once a fortnight. I have no issues.

Dont touch it perhaps?

Not the best solution.

Ordinary microfibre cloths leave residue, which can get awfully pesky when driving towards sunlight.

You obviously drive a lot with the windows down. Keep them up if you want cleaner glass!

There are specific microfibre cloths designed for use with glass. Use that according to instructions, some say to use with just water, but I find using it with a car specific window cleaner works fine for me.

Failing that, black and white newspaper with windex works treat also. Safe for tints.

An alternate method is warm soapy water with rung out rags use environmentally friendly dish washing liquid. Once over the window, then once over with just the warm water and then once over again with a dry cloth or micro fibre. This way it will help to remove the residue and gunky build up. I found that windex etc gets into the gunk but does not help to remove it but rather degrade or smudge it away. This is not good for muggy looking windows.
  Next step if they are still stuffed is to go over them up to five times. You will never see cleaner windows in your life.

I use the Auto Glym glass polish to, goes on and off nice and easy and leaves no greasy marks..

Thanks y'all. I've got tinted windows on the side/back, might just have to use some elbow grease for that.

massive myth???
i heard a while ago to cut a potato on half and smear it all over the window, then do the soapy water thing. Apparently the starch in the potato does something to the built-up grime.
I have never tried it myself, someone else should give it a go then let us know.

Sounds messy! I wouldn't like to be getting that potato starch off if it dried out!

I've heard of people using a potato to stop the windows fogging up or to stuff down their budgie smugglers but never for cleaning, every time I go to the beach I stuff one down the back of mine but the girls just laugh at me.........so that doesn't work either:Derisive:
