Cleaning agent for fire-arm barrels based on ammonia or amine compounds, in particular for the removal of abraded shot or bullet material. In order to achieve a simple and non-dangerous application and to improve storability, the ammonia or amine compound is contained in a high viscosity gel. An improved cleaning action can be achieved when the gel additionally contains a grinding and polishing agent with a mechanical effect, for example cerium oxide or very finely pulverized silicon dioxide.
