True, but it did the damage in a matter of seconds... thicker plexi would only take a bit longer... right?
Generally windex included will cause crazing ... Crazing is small fractures in the acrylic.. Even after discontinued use of the cleaner the crazingf never really stops.
The acrylic crazing gets to a point where it eventually fails.. There is no real study on how long taht I have found .. As it varies.. There are acrylic polishes and cleaners that are cheaply found as windex and other cleaners and are better
I know peopel that actually use acetone to weld acrylic
Oh and windex in my opinion is a no no anyway Mysteriously people tend to lose fish more often when using windex to clean their tanks.... Glass or a acrylic.. This is just my opinion and own conclusion from reading

This is just my opinion and own conclusion from reading Here is a little science and fact to back up my conclusions As I am sure everyone that has had glasses has noticed the effect of windex and alcohol on different lenses
But anyway.

Chemical Resistance
Acrylic is resistant to a wide range of chemicals including salts, bases, aliphatic hydrocarbons, fats and oils, most common gases and inorganic chemicals, dilute mineral and organic acids, and dilute and concentrated solutions of most alkalis. It is attacked by strong acids, chlorinated and aromatic hydrocarbons, ketones, alcohols, ethers, and esters. Of course, the chemicals and other materials to which a molded part will be exposed should be carefully considered before selecting any thermoplastic.
Isopropyl alcohol tends to promote crazing in acrylic, as it does in many transparent plastics. Some acrylic grades are more alcohol-resistant than others: resistance is typically a function of the molecular weight of the polymer, with higher molecular weight providing better alcohol resistance. Diluted solutions of isopropyl alcohol can be used to wipe down acrylic without adverse reaction. Acrylic copolymers, particularly those with styrene, offer improved chemical resistance but do not transmit light as well as 100% PMMA.
