After you discover adhesive on your laminator's rollers there are a few things you will need to clean the rollers: a Scotchbrite pad, denatured alcohol and a lint free cloth.  Apply the denatured alcohol to the Scotchbrite pad and gently rub the rollers until the adhesive is removed.  Be careful not to damage the roller by rubbing too hard.  When the adhesive has been removed wipe the roller clean with the lint free cloth.  Please do not use exacto blades or straight edges to clean your rollers.
