Blue painters tape is like ‘easy mode’ for PLA, in particular Scotch Blue seemed to work the best out of the brands I had on hand back when I was doing PLA a lot.
It also protects your glass bed, I have had ABS stick so tight to just a clean glass bed (alcohol cleaned like vicious1) that it ripped out chunks of glass and cracked the whole thing. There is one part on my MPCNC now with borosilicate glass merged with it. PETG has done the same thing to a lot of people. With blue tape on there it just pulls up on the tape instead of breaking glass when things stick too good.
