Quick Answer
To clean an 8x57 Mauser after a day in the field, start by removing the magazine and clearing the chamber, then wipe the rifle's exterior with a soft cloth to prevent rust. Next, disassemble the rifle and clean the bolt, action, and barrel with a solvent and a brush, working from the breech end forward. Use a clean cloth to wipe away any remaining debris.
Removing the Magazine and Clearing the Chamber
Begin by removing the magazine and checking to make sure the chamber is clear. If you’ve fired the rifle, it’s likely that a spent cartridge will be lodged in the chamber. Use the bolt to extract the spent cartridge, and then insert a cleaning rod or a chamber brush to ensure the chamber is clear. This is an important step to prevent any accidental discharges when cleaning your rifle.
Cleaning the Bolt and Action
Use a solvent, such as Hoppes No. 9, to clean the bolt and action of your 8x57 Mauser. Apply the solvent to a cleaning cloth or brush and work it into the bolt’s locking lugs and the action’s surfaces. Use a soft-bristled brush to scrub away any stubborn grime or debris. Then, use a clean cloth to wipe away any remaining solvent and grime. Repeat this process several times until the bolt and action are clean.
Cleaning the Barrel
To clean the barrel of your 8x57 Mauser, use a cleaning rod with a jag and a patch. Apply a small amount of solvent to the patch and attach it to the jag. Insert the cleaning rod into the barrel and push it through to the muzzle, working from the breech end forward. Repeat this process several times, using a clean patch each time, until the barrel is clean.
