One of our commercial accounts asked me yesterday if we could clean the downstairs window frames and sills with a  specialist cleaning product even though we already clean the whole 36 three story apartments WFP.  It's a privately managed property but the windows in question are near lots of trees which accumulate lots of sap etc.
Any advice on which product to use?

If you dont know how to clean windows after all these years then theres no hope for you.....🤣🤣🤣

I'd use virosol  in a spray bottle and hot pure water......

Virosol should do it. Hot or cold water. Rub in , leave for 5mins. Scrub off, spray down.

Unless they are  almost beyond help hot water you shouldn’t need any chemicals tbh if you use hot water,if you are using cold I would spray on either as said Virisol or a normal truck wash type detergent,failing that tell them to take them out and have them replaced.
