Typically, there is a little buggery dot of glue that has formed in or on the tip. Simply use your fingernails and literally “pull the plug”! This plug may be what keeps the glue from drying out when it is uncapped for long periods of time. Occasionally, when there is a real clog, use a paperclip or pin to open the tip. Thankfully, this doesn’t happen very often! If your cap is really gunked up, you can wash out the liquid glue out with soap and water. Then fully clean the cap with THE BEST CLEANER EVER™.
