UTG's Airsoft Silicone Spray Oil is excellent for airsoft cleaning and lubing.  This 100% silicone product contains no petroleum distillates that could harm your sensitive airsoft parts, unlike many store-brand silicone sprays that do.  Small 50ml bottle will last you a long time and is small and convenient for carrying onto the field as well!  This product is ESSENTIAL for keeping gas blowback pistols properly cleaned and lubricated.  It is also commonly used for cleaning inner barrels on all airsoft guns as well.CLEANING YOUR BARREL! When cleaning your barrel, we don't recommend spraying the silicone directly down your barrel, as you may end up spraying to much into your gun.  We recommend using a cleaning rod and a cleaning cloth.  Insert the cleaning cloth through the hole in your cleaning rod, and spray the cleaning cloth with silicone until it is wet.  Make sure to reduce your hopup to its lowest setting in order to lift the hopup out of the barrel so your cleaning rod doesn't get caught.  Insert your cleaning rod with the cleaning cloth first, and move the cleaning rod into your barrel.  It is also good to spin or rotate the cleaning rod at the same time as it helps more thoroughly clean your barrel.  Once you reach the end, remove the cleaning rod, replace the cleaning cloth, and repeat until you no longer see dirt or other debris on the used cleaning clothes.
