Canadian Restricted and Non-Restricted Firearm Safety (CRFSC) Practice Exam

The best practice for cleaning a firearm is after every use. This is essential for maintaining the firearm's performance and safety. Regular cleaning prevents the buildup of residues from gunpowder, lead, and other materials that can accumulate after firing. These contaminants can lead to corrosion, malfunctions, and safety hazards if not addressed promptly.

Additionally, consistent cleaning allows the shooter to inspect the firearm for any signs of wear or damage that could require attention, ensuring that it remains in optimal working condition. By making it a habit to clean the firearm after each use, the owner promotes reliability and longevity of the firearm.

The other options suggest less frequent cleaning, which may result in neglect and potential issues. For example, only cleaning when the firearm looks dirty may overlook the damage that can happen from moisture or residue buildup that's not immediately visible. Cleaning it once a month or just before going shooting does not account for the potential dirt and wear that can occur in between those intervals, thus increasing the risk of malfunction during use.
