This can happen on a wooden window, where polyurethane varnish on the frame gets on the glass. Unfortunately, once polyurethane cures, it won't dissolve in anything, which is one of the things that make it so good. If you want it off your glass, you've got to use a razor-blade scraper and scrape it off. You could try using acetone (or MEK, if you can get your hands on some). It won't actually dissolve the polyurethane, but it may soften it a bit and make mechanical removal easier.

Is Polyurethane foam Hypoallergenic?
Polyurethane foam can potentially trigger allergic reactions in some individuals due to its chemical composition and off-gassing. It may not be considered hypoallergenic for those sensitive to chemicals or respiratory irritants.
The solid that dissolves in a liquid is it solute solution solvent insoluble?
A solid that dissolves in a liquid is called a solute. The term solute means that which is dissolved. A solution is the resulting mixture of solute and solvent. A solvent is that which dissolves. Water is the most common solvent; if sugar dissolves in water, then sugar is the solute and water is the solvent. The term insoluble means does not dissolve, so for example, glass is insoluble in water. That's why you can pour water into a glass and the glass remains intact.
What does Hydrofluoric acid do to glass?
Hydrofluoric acid can react with glass by forming silicon tetrafluoride and water, which weakens the glass structure. This can lead to the glass becoming etched, corroded, or even cracked. It is important to handle hydrofluoric acid with caution when working with glass to avoid damage.
How do you remove polyurethane from fabric?
You can remove polyurethane from fabric by scraping off the excess using a rubber scraper. Use the blade of a sharp knife to further remove the top layer of polyurethane. Then, apply acetone to the stain and allow it to work for 10 minutes before rinsing the fabric with water. If the fabric is white, soak it in bleach and water for 30 minutes, then wash as usual.
Are all solids equally soluble in the same solvent?
Absolutely not! Using gasoline as a solvent, wax dissolves in it but glass will not dissolve at all. Using water as a solvent, salt dissolves in it but pepper will not dissolve at all. Using hydrofluoric acid as a solvent, glass dissolves in it but wax will not dissolve at all.
How do you clean polyurethane off glass windows?
To clean polyurethane off glass windows, you can use a razor blade to carefully scrape off the excess polyurethane. Be sure to hold the blade at a low angle to avoid scratching the glass. After scraping, use a mixture of warm water and mild dish soap to clean the remaining residue, followed by a glass cleaner for a streak-free finish.
