Remove/reverse wiper delete

[PP200t]

I’ve searched the interwebs and got nothing so I’m turning to the minds of cs.
Does anyone know how to remove a rear wiper delete and return to standard please? I’m thinking a thin blade to cut the silicone, but I’m worried I’ll smash the screen.
Thanks in advance.

Heat gun? Might be able to soften and remove with a plastic tool before going in with anything sharp

Fishing line if you've got some, guess cotton/dental floss could work

I removed my passat one with a Small craft knife. On eBay for about a quid.
Make sure you use a brand new one that’s sharp.
(Never done it on a clio but they’re all much of a muchness)

Sorry, I should’ve said it’s a flush plastic/glass one on a focus. 🤦 so the other suggestions won’t work. Thank you though.
@The Crumb Master So run the blade around the slight gap between glass and delete and then push? That’s a good idea.
