Previous owner covered windows with packaging tape — now it's completely dried and won't come off. Help!
Hi! We recently acquired an older house, and we're having a hard time removing dried packaging tape that the previous owners used to cover the windows. The tape has been there for years and has become extremely brittle and stuck to the glass.
We've already tried several methods, including:
\- Warm water with vinegar and dish soap, combined with a heat gun/hot air blower
\-Thinner
\-Goo Gone adhesive remover
\-Scraping with a blade
While we've managed to remove some of it, a lot of the residue is still firmly attached, and scraping harder doesn't seem to help.
Has anyone dealt with old, dried packaging tape on glass before? What method or product worked best for you? We have multiple windows to clean, so we're hoping to find an effective solution.
Thank you!
