Good afternoon from SE- PA. Have accumulated 3k on '12 Compass,and am enjoying vehicle almost as much as wife is (she's the primary driver). Filled winshield washer resevoir w/ Rainex brand ww fluid day after we took delivery from dealer. Have used this product in our vehicles since its entry onto market. This week on one of our unseasonally warm days I decided to clean windows. Usually use sprayfoam cleaner, from Autozone,w/ terrycloth followed up w/ papertowels. Cleaned,or so I thought, all glass int/ext & prepared to walk away satisified w/ job. Sunlight caught streaks on glass,(wth)repeated process. Same streaks. Tried Windex,same crap. Tried amonia/alcohol/vinegar mix I used to use,same results. Went on to try alcohol strait,laquer thinner, even zylene! I cannot remove this "film" from the glass. I have a few hundred window cleanings under the belt,so I know how to clean same & usually get great results. I suspect the culprit is the Rainex. If it contains silicone in any form it will be tough to eradicate from glass. Anyone else have any problems w/ Rainex??? Open to suggestions. Thank you for your time.

First I am no window cleaning expert and clearly and when you said "Went on to try alcohol strait,laquer thinner, even zylene!" well I would never try that because it seems way out there putting laquer on glass. But Vinegar in water etc is an old moms cleaner that works.

I suspect you may have exactly what you suspect from Rainex. Suggestion from a somebody... Dawn dishwashing liquid is used washing cars to strip wax etc before a clay cleaning etc. I might just remove that after a good going over. I would risk saying trying it will not do any damage to your Jeep. Otherwise contacting Rainex would be the next step to remove it or wait and it may or should eventually wear away.

Cheers I hope this helps as there were not other replies.

I don't like putting weird super cleaners in my washer jar. Some could compromise the O-rings or pump. I know decades ago I'd put a bit of dish washing soap and found it created a film/scum withing the washer jar pluging the pump input etc. So I've stopped that sort of thing. I clean the windows with blue windex at times but the various other types they make leave streaks or some clouldyness. The old fashion blue works ok. My son bought some glass cleaner for autos in a spray can which is excellent with crystal clear results. I use it now and then.

Answer to own question!

Talked causally to an old aquaintance from the university I retired from. He's in the chem lab in their earth sciences dept. Seems the Rainex residue may be reacting w/ the UV. Causing a kind of soup-residue. Tried the dish deterg idea and whoa!, it worked like a charm. Am returning to amonia-ETOH-vinegar brew for windows from now on. Thanks to all who tendered advice. The Compass pictured in one post is a duplicate of ours. Again thank you all.

Good to hear its gone. We have a winner.

Further to the glass cleaning. If you after a excellent commercial product which is a spray aerosol can. I can vouche for STONER - Invisible Glass, STONER being the manufacturer in Quarryville, PA

My son bought a pack of these at Costco's a few years back. They make Windex clean look like road slope in comparison. It comes of crystal clean/clear inside or out. For the amount we use I'd say its worth it.

Nothing like clean windows in foul weather or night driving. :canada:

I took the effort to find their website for the product. You'll find it on this page. I have not read their blurps etc but use the Invisible Glass with great satisifaction. http://www.stonersolutions.com/
