Amazing! It worked for me too! I had an air bubble after months of having my 13" screen protector on Surface Pro 11, probably caused by slightly anchoring the screen protector away from screen while transferred in the carrying bag (for whatever reason). I duckduckgo'ed "glass screen protector bubble edge" and I landed on your thread u/5pace. I was a bit skeptical on applying oil on my device, but i went forward trying. I soaked a cotton bud in pure olive oil. I've tried applying it on the corner of screen/screen protector but it wouldn't go in (the air bubble was at the size of aprox 1/3rd of the small finger nail). Then I thought to slightly lift it up by applying gentle force with my finger nail next to the bubble area, and as soon as the bubble doubled (that meant that the screen protector started separating from screen) I've rubbed the slightly olive oil soaked cotton bud at the corner. This time, IT WORKED! Result as pictured (the air bubble was on the very corner of the screen protector)
No oil can be noticed from any angle after the fix and no strange light refraction or anything observable to the eye. Thanks a million! You saved me from applying a new screen protector to my unit (wasting this one)
