Hot glue guns are versatile for various crafts, DIY projects, and repairs. Over time, residue from melted glue can build up inside the gun, affecting its performance and longevity. Proper maintenance, including regular cleaning, is essential to ensure the smooth operation of your hot glue gun. In this article, we will guide you through a step-by-step process of effectively cleaning the inside of a hot glue gun.

Materials Needed:

Before we begin, gather the following materials:

  1. Clean cloth or paper towels
  2. Cotton swabs
  3. Rubbing alcohol
  4. Small brush or toothbrush
  5. Needle or pin
  6. Safety goggles (optional)

Step 1: Disconnect and cool down the glue gun

To ensure your safety, unplug the hot glue gun and allow it to cool down completely. Never attempt to clean the gun while it is still hot, as it can cause burns or damage to the internal components.

Step 2: Remove the glue sticks and inspect the nozzle

Check any remaining glue sticks in the gun and remove them carefully. Inspect the nozzle for any visible chunks of dried glue. If there are large residues, use pliers to pull them out gently. Please do not force the glue stick through the nozzle, as it may damage the gun.

Step 3: Wipe the exterior of the glue gun

Take a clean cloth or paper towel and dampen it with rubbing alcohol. Wipe the exterior of the glue gun to remove any dirt, grime, or adhesive residue. This step is crucial to maintain your hot glue gun’s overall cleanliness and appearance.

Step 4: Clean the nozzle

Using a cotton swab soaked in rubbing alcohol, clean the inside of the nozzle. Gently rub the swab along the inner walls of the nozzle, removing any accumulated glue residue. Repeat this process until the swab comes out clean.

Step 5: Clean the feed chamber

Next, focus on the feed chamber where the glue sticks are inserted. Use a toothbrush or a small brush to remove loose debris or dried glue particles from the chamber. Be gentle to avoid damaging the heating elements or other internal components.

Step 6: Unclog the feeding mechanism

Sometimes, glue residue can clog the feeding mechanism, hindering the smooth flow of glue. To fix this, take a needle or pin and carefully insert it into the feeding mechanism, applying gentle pressure to dislodge any obstructions. Be cautious not to damage or scratch the metal parts while doing so.

Step 7: Remove stubborn residue

For stubborn residue that doesn’t come off easily, dampen a cotton swab with rubbing alcohol and rub it over the affected area. Let the alcohol sit for a few minutes to soften the glue. Then, gently scrape away the residue using the needle or pin. Be patient and avoid using excessive force to prevent damage.

Step 8: Final cleaning and reassembly

Once you have cleaned all the internal components, use a clean cloth or paper towel to wipe away any remaining glue or alcohol. Ensure that the glue gun is completely dry before reassembling it. Insert new glue sticks into the feed chamber, ensuring they fit securely.
