Remove debris from print bed
I had an issue removing the first layer (abs in my case) from the print bed and came up with this idea, which worked great for me:
Create a 2 mm high square of the same material covering the area you like to clean. Set layer height to 0.3 mm (also first layer as there is already some stuff on the print bed)
Print normally and as soon as it is finished, tear the square off the print bed right away. The square is still hot and somewhat soft and it will take the debris with it.
To get a good grip, you can make the square with a 45 degrees edge.
Do not add support and set the skirt loops to zero else you will end up with the issue you tried to solve in the first place.
If you need to clean a large area, do it with a maximum of about 40mm x 40mm at the time. Larger squares will remove more difficult.

If you do not let the bed/steel plate cool down, you will damage the at least the pei sheet, the sticker will be damaged.
the idea is to let the steel plate cool down, and then the model will come easy loose from bed.
If it is not so(petg), then use window cleaner or glue stick so model will not stick to the bed so hard.
Try to clean with dish soap, a few times.

Ok. I used it on the powder coat plate.
