Removing glue residue on part after printing Following advice I read elsewhere, I have covered my (heated) print bed with blue painter's tape, and before each print I apply an Elmer's purple washable glue stick to improve bed adhesion.

After the print finishes and I remove the part from the bed, the bottom is covered with a white residue. I'm fairly certain this is the dried glue. It turns purple again when I wet it.

Is there an easy way to clean off this residue, or is there a better technique?
Elmer's Purple Gluestick is pretty much based on PVA with a water-indicator. It is a water-soluble material. Tossing the piece into a water bin and brushing it with a toothbrush should remove everything.
