How Do You Clean an Epoxy Spray Gun Nozzle?

Step-by-Step: Cleaning Your Epoxy Spray Gun Nozzle

Begin by carefully removing the nozzle from your spray gun, following the manufacturer’s instructions. Soak the nozzle in a suitable cleaning fluid—Pure Isopropyl Alcohol 99.9% is widely used for resin projects thanks to its efficiency. Allow the nozzle to soak for several minutes to loosen any stubborn residue.

Use a soft brush to gently scrub the inner and outer parts of the nozzle, paying close attention to small openings where epoxy tends to collect. After cleaning, rinse thoroughly with clean isopropyl alcohol or water and allow the nozzle to dry completely before reassembly.

Best Tools and Products for Effective Cleaning

• Isopropyl alcohol (99.9% pure): Quickly dissolves resin residue without leaving marks, ideal for precision cleaning.
• Soft brushes and microfibre cloths: Microfibre cloths are gentle, lint-free, and perfect for wiping clean without scratching surfaces.
• Natural degreasers: A natural formula degreaser can help remove grease or silicones that build up on tools and surfaces.

When Thorough Cleaning Matters Most

Regular and thorough cleaning of the spray gun nozzle is vital after every use, especially when switching between epoxy types or before any long storage period. This prevents hardening of leftover resin, which can cause future blockages and uneven spray patterns.
