How to Clean Nozzle and Needle Components of Your Epoxy Spray Gun

Step-by-Step Guide: Cleaning Nozzle and Needle Components

Start by disassembling your spray gun according to the manufacturer’s instructions. Carefully remove the nozzle and needle, paying close attention to how they fit together for easy reassembly. Use a dedicated cleaner like Pure Isopropyl Alcohol 99.9% to dissolve any residual epoxy, ensuring you reach all crevices. A small brush or soft microfibre cloth can help gently scrub away stubborn build-up. Allow all parts to dry thoroughly before putting the spray gun back together.

Recommended Tools and Products for Thorough Cleaning

• Isopropyl Alcohol: High-purity alcohol is highly effective for breaking down resin residue on metal parts.
• Natural Degreaser: For heavy or greasy build-up, consider a plant-based, solvent-free degreaser for a gentle yet thorough clean.
• Microfibre Cloths: Lint-free cloths are perfect for wiping down delicate components and ensuring no fibres interfere with your next project.

When This Matters Most

Giving extra attention to cleaning the nozzle and needle is crucial when switching between resin formulas or after spraying particularly viscous mixes. Frequent, careful cleaning can prevent clogging and ensure a smooth spray pattern, making all the difference for professional-quality finishes.
