It also helps to clean the build plate from time to time too. Over time grease from your fingers will make it onto the surface (no matter how careful you think you are). Some filaments also seem to leave behind an oily residue that builds up after a few prints. I haven't done much research on what I should be using so I have a bottle of iso and a sponge that I use to wipe down the surface. (A microfiber cloth would probably be better).
