Your lid should never have any black residue on it or you will eventually not be able to open your bottle. This is entirely preventable!
Step 1: Hold your bottle upright and puff the bottle a couple of times to clean the inside of the nozzle.
Step 2: Wipe down the outside of the nozzle
Step 3: Use a lint free applicator to clean the inside of your lid
We recommend storing your adhesive on a dark air tight container
