There are little holders for double bladed razors that make them useful as box cutters, general tape cutters, caulk breakers, and when your surface isn't delicate they can be used as scrapers.
Something like this thing but with steel blades instead of plastic.
Try this tool. It is plastic razor blades that can help remove the resin and are a little safer to use on the screen https://www.amazon.com/gp/product/B01HLWB0BM/ref=ppx\_yo\_dt\_b\_asin\_title\_o04\_s01?ie=UTF8&psc=1
The best method I found to get them off was to warm them up, then carefull scrape them off with a plastic scraper (like this: https://www.amazon.com/Ehdis-Visibility-Plastic-Scraping-Windshields/dp/B01HLWB0BM/ref=sr_1_18?dchild=1&keywords=plastic+scraper&qid=1629659110&sr=8-18 ).
I got the remaining residue off with a decal remover wheel on my drill (like this: https://www.amazon.com/SATC-Removal-Adhesive-Remover-Graphics/dp/B07ZNGPY8G/ref=sr_1_5?crid=1BVDM7STPUZG1&dchild=1&keywords=decal+remover+eraser+wheel&qid=1629659165&sprefix=decal+remover+%2Caps%2C261&sr=8-5 )
After that a quick wipedown with some Isopropyl and you're ready to mount the new ones!
I clean over a thousand Lenovo X1 series laptops a year that have been used by college students for 2 years, and then need to be returned for the end of their lease. I swear by Goo Gone and a non-damaging plastic scraper that cannot gouge the surface material like:

Goo Gone is almost all orange oil and kerosene as its active ingredients. It can't dissolve the PC + ABS plastic that the T series palmrest should have, and does not contain acetone.
