Which tool is recommended for cleaning holes in an air cap?

Using a toothpick to clean holes in an air cap is an effective method because it allows for precision and control in removing debris without damaging the delicate structure of the air cap. Air caps are crucial for proper spray pattern and atomization in painting, and any blockages can negatively affect performance. A toothpick can effectively dislodge small particles without the risk of scratching or altering the precision-engineered holes.

While other options may appear practical, they do not provide the same level of care or suitability for this task. A metal brush might be too abrasive and could potentially damage the air cap. A high-pressure air hose, while effective at blowing out larger particles, might not be able to reach the small holes effectively and could even push debris further into the system. Using water and soap solution is generally unsuitable for this kind of maintenance since moisture can cause damage to the air cap and may leave residues that could further impede function. Thus, the toothpick stands out as the recommended tool for cleaning air cap holes effectively and safely.
