Most of us here use hairspray on top of glass
I don't know what type of surface the Workbench comes with, but most of us now use glass.
Get a piece of glass cut to the size of your print bed surface (2-3mm thick works great).
Remove any Kapton tape or any other surface covering that is already on the bed, then spray some hairspray on the bottom side of the glass, then put it on top of the print bed. Heat up the print bed, then let it cool off, then heat it up again, and let it cool off.
The glass should be attached to the print bed pretty well. Next spray a good layer of hairspray on top of the glass, heat up the bed and let the spray dry on the surface (about 5 minutes should be good). You should now try to print something.
To remove the printed mode, simply wait for the prinbed to cool off, once it's cooled off, the model should easily pop off. You only need to spray the top of the glass once every few prints, but if you want to do it before every print that works too.
If you want to take the glass off the printbed, heat it up, and when it's hot, gently slide a thin blade between the glass and the bed and separate it.
Good luck
P.S. for PLA, We found that Blue painter's masking tape works great, and now heat is needed. Just pay a few layers of blue tape on the surface, and print straight on top of it, no hairspray or glue needed.
