How To Clean A Dried Up Expanding Foam Gun

If you’ve ever used an expanding foam gun, you know how important it is to clean it properly after each use. This prevents the foam from drying up and clogging the gun, ensuring its longevity and continued effectiveness.

When a foam gun becomes clogged with dried foam, it can be challenging to remove. However, with the right techniques and tools, you can easily clean it and restore it to its original condition.

The first step in cleaning a dried up expanding foam gun is to disassemble it carefully. Unscrew the gun’s tip, needle, and nozzle, and remove any foam residue that you can easily reach. Be sure to wear protective gloves and goggles to prevent any foam from coming into contact with your skin or eyes.

Once you’ve removed the visible foam residue, the next step is to soak the disassembled parts in a foam gun cleaner. This cleaner is specifically designed to dissolve dried foam and unclog the gun. Follow the manufacturer’s instructions on how to use the cleaner and let the parts soak for the recommended amount of time.

After soaking, use a brush with stiff bristles to scrub away any remaining foam residue. Pay special attention to hard-to-reach areas and ensure that you remove all traces of dried foam. Rinse the parts thoroughly with water to remove any cleaner residue and allow them to dry completely before reassembling the gun.
