Nasty Film

[rtbickel]

I apparently cleaned the windshield on my 1400 with something funky - no idea what - and it has now developed a streaky film on both sides that can be buffed out fairly quickly with a soft cloth, but it comes back after just a few minutes.  Any suggestions on what I could apply to cure the problem?

Try some warm water and vinegar with a soft microfiber towell. Worked for me.

I'd be interested in the windshield solution.

Whether or not this is a solution for your Guzzi.....

if you ever use a product like Super Clean, Purple Stuff, Purple Power on an original or aftermarket HD windshield, it's game over.  Even if diluted, applied to wet windscreen, whatever...  It will forever have the described milky, streaky haze when it dries.  Sometimes it will seem to buff out or go away when using some magic elixir but it won't last.  You'll buy a new windshield and hopefully not do it again.  Or you'll buy another new windshield and hopefully not do it again. 

Keep your windshield cleaning products in a special place and if you don't know what it is, don't use it on a plastic windscreen.

You might consider plastic polish.

MEGUIAR'S plastic cleaner then followed by Meguiar's plastic polish.  If that doesn't do it then a new windshield is in order.

As you may be aware, a replacement windshield is pretty expensive. Last option for sure. Besides the ideas already put forth, You might try tooth paste with a wet wash cloth. I would strongly suggest you test a small place on the shield to make sure you don't make things worse before you tackle the whole thing though. The tooth paste acts as a fine polishing compound. I have used it in the past on car glass to remove road grime that would cause streaking and visibility issues. I have not to the best of my recollection tested it on plastic. So, I say again, if you try this test a small area in some obscure spot first.

edit: Another thing I used to do was use Comet. Again, use caution. Both are a mild abrasive.

I would start with a strong mix of dishwashing liquid.

I had the same issue this winter with my CV1400 Touring shield.  There was just so much rain and moisture every time I pulled the cover the film was there.  The first decent day I scrubbed it from top to bottom with just warm soapy water and started polishing it with just a clean microfiber cloth.  The film disappeared and I just touch it up now after riding with the same format.....So far so good......

I use this stuff called White Diamond a metal polish. Takes the light scratches out and polishes up nice and clear. It's what I use on my wife's headlights on the car to get rid of the haze and fog.

I've used Semichrome polish for years with good results.  A little dab on the fingertips & work with a circular motion. Do a small area at a time.  Buff with an old t-shirt & you're good to go.

Made for finishing plastic. Standard remedy for damaged aircraft windscreens.
#2 was the abrasive of choice for general repair.
Some plastics are "hardcoated" (like eye glasses) and abrasive cleaning will destroy the hardcoat. Shoei visors are one example. Don't know about bike windscreens but wouldn't be surprised to find that the better ones were. It does make them more abrasion resistant. The chemical fogging might be a reaction with a surface coating as most plastics don't tend to react with detergents (only solvents soften them).
Best luck.

If its acrylic it will polish, its its polycarbonate put up with the haze/scratches or replace it with a new one.
Warm soapy water, your hand and a chamois type cloth are all you should use.
Spent many years polishing perspex (acrylic) aircraft canopies and windows, and changing buggered polycarbonate ones.
