How do you get melted polyester off glass?

To remove melted polyester from glass, first allow the glass to cool completely. Then, gently scrape off the melted material using a plastic scraper or a razor blade held at a shallow angle to avoid scratching the glass. If residue remains, apply a mixture of warm water and dish soap to soften it, or use a commercial adhesive remover. Finally, clean the glass with a glass cleaner to restore its clarity.
