Boat canvas window cleaner

[Attitudeboy2]

Hello everyone, hoping I can get some suggestions on what to use to clean the clear window portion of my high rise canopy. I have an ‘06 542 Explorer and over the winter the front window portion of the topper has what looks to be hardened pollen stuck to it. I have tried simple hot water and soap without success and was looking for some suggestions on what others have used and not damaged it.
Thanks in advance.

Not sure what you should use on that. Can you use a razor blade to scrape it off without damaging it? Once it is clean, Lemon Pledge is a great product for keeping it looking good.

Try bug spray. I’ve never done it personally but saw it on IG being used on plastic headlight lenses. It did an amazing job. Think they used “Off”. Experiment first with a small area.

They used to make a 2 step version. If it too far UV degraded it might not get back to new condition? I googled “Clear Plastic polish” and got a few options. Amazon sells a few.
