Maybe you are leveling the bed too close to the nozzle. Google some pictures of how a good first layer is supposed to look like and move the bed a little lower so that the first layer has good adhesion but isn't forced into the bed.

Are you letting the bed cool before removing? That can help a lot.
What type of bed do you have? If it's a flexible one, just take it off the printer and flex it/peel it off.
As a bed scraper, I use a putty knife that I've sharpened on one side (chisel grind, #4).
Before printing too-sticky materials (like TPU on my PEI bed), I put down a layer of glue stick. This is sticky enough for successful prints, but easily removed at the end of the print.
As an extra hint, if you have a sticky print don't try to smash and stab the putty knife at it, instead grab a hammer/wrench/anything really and gently tap it under the print. It releases so, so much easier.
I would recommend a PEI print surface like this: https://www.amazon.ca/gp/product/B08L39BFVJ

EDiT: I should say I only ever printed with PLA since I got the PEI sheet. I know PETG can bond to a PEI surface, so be careful with that.
Chances are you are squishing too much first layer, so adjust that first. Then print over residue with slow speed and 5-10° hotter than usual settings. Residue should come off with print.
