Airbrush Kit Cleaning and Maintenance Methods: Add water, alcohol, or cleaning solution to a spray bottle and apply.Try a reverse flush. Cover the nozzle with your finger or a tissue and gently press the trigger. This helps clean the narrow cavity around the needle. Please note: Do not use the airbrush while it is charging.Test the airbrush gun with water before use to ensure it is not clogged.When the spraying work ends or stops for more than 10 minutes, please make sure to thoroughly clean the spray gun chamber, nozzle, and liquid cup promptly.After 30 minutes of continuous use, the air compressor should be turned off for a few minutes to cool down.Please use water-based foundation instead of oily foundation. It is recommended to use a spray gun foundation to prevent nozzle blockage.Do not soak your gun while cleaning. Although this may sound like a simple cleaning solution, doing so can actually damage the more sensitive parts of the tool.If the gun does not spray liquid, it may be because the fluid control knob is too tight or the nozzle is blocked. Try adjusting the three fluid control knobs or cleaning the nozzle with alcohol or detergent.
