Digital BW, The Print

The issue with an unknown formula, in this case Windex, is that the product also has trace amounts of cellosolve, along with perfume, water and alcohol.  I'm not sure, as the formula may have evolved, but there could even be traces of DEP - but I doubt it.  You will note that the Windex container is PETE. In the old days it was glass, and later a plastic was used, that over time would deform.

The issue is with the long term contact of cellosolve and perfume with the plastic. I would suggest you take a broken piece of reference plastic and place it in a sealed jar.  Store in a warm environment, say 45C for 6-8 weeks, then observe the plastic's condition.  Long term contact soften / dissolve the plastic.

Windex is designed for glass, and is not a leave on product. You can use it on plastic, but a wipe off is expected. Hence you need to perform a test with the substance on which the Windex will be in long term contact.

I think the key with Windex, is the alcohol/water ratio.  Alcohol is the solvent of choice.  Butyl cellosolve is a great cleaner, but you need to flush out the product after use.
