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.
