Ballistol 500 ml effectively dissolves and neutralises the residues of burnt gunpowder. The agent is particularly recommended for silencers with non-expandable construction.Even the best silencers will clog up after a while, increasing friction and slowing down the fired projectile. Regular maintenance of the silencer is the best way to ensure optimum performance. The problem arises when the silencer is not of a separable design, which obviously makes it difficult to access tight areas. In such a situation, it makes sense to use Ballistol Professional Exhaust Cleaner, which effectively dissolves, removes and flushes out all the stuck-on dirt. The product is acid-free, odourless, inert and surfactant-free on most materials.exhaust cleaner dissolves and neutralises burnt gunpowder residuesoperates automatically without dismantling silencerseasy and effective to usebased on acid-free, inert, surfactant-free active ingredientsoperates spontaneously after only 2 hours.How to use Ballistol Exhaust Cleaner?Dismantled exhausts - after dismantling the exhaust, the components are immersed in the cleaner and left for about 2 hours (normal contamination). Ballistol Exhaust Cleaner can also be used for cleaning in an ultrasonic cleaner. Non-sealable mufflers - the muffler is plugged in tightly on one side (e.g. with an ear plug), then filled with Ballistol Cleaner and left to stand for 2 hours. The usual dirt will dissolve after about 2 hours. After this time, the cleaner is removed from the exhaust, half-filled with warm water, the outlets are plugged again and shaken vigorously. After cleaning, it is recommended to use an exhaust surface conditioner. If the exhaust is heavily contaminated, the product can be heated to 40 °C and left in the exhaust for a longer period, for example 4-8 hours, before application. In the case of very dirty silencers, the application time can be extended up to 24 hours. Note 2: Before using the cleaner properly, check its reaction with the silencer material in an inconspicuous place. A change in the colour of the detergent is a normal phenomenon indicating the dissolution and neutralisation of the contamination.
