<p>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.</p>

<p>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.</p>

<p>Is there an easy way to clean off this residue, or is there a better technique?</p>

The print stick so well to one of them that I end up ripping the tape up to get it off and the bottom of the print has the tape suck to it. The other roll was the complete opposite, nothing would stick to it. I ended up using the non-stick tape and applied a diluted (30% PVA - 70% water) glue to the (tape covered) hot bed. Works wonderfully.</p>\n\n<p>Mike.</p>\n'}]
