How to Clean a Ruger P89 Pistol

The Ruger P85 is a dependable semiautomatic handgun featuring a stainless steel action and sophisticated design. Like all other firearms, after being shot it should be cleaned to prevent internal degradation and loss of accuracy. Luckily this process is not a difficult one, and with these step-by-step instructions you can be sure your P85 remains in top condition.

    Before cleaning, inspect the P85's chamber to ensure it is not loaded. Make absolutely sure there is no round chambered before attempting to clean the gun.

    Locate your P85's instruction manual and look up the fieldstripping procedure. If you cannot locate the instruction manual, it can be found online along with various unofficial fieldstripping procedures.

    Disassemble your P85 as detailed in the fieldstripping procedure. This allows access to the firearm's internal working parts which, as a rule, should be cleaned every time the barrel is.

    Dip a patch in cleaning solvent and run it through the barrel several times with the rod from your cleaning kit. Repeat with a second solvent-dipped patch, and then remove the solvent by running a clean, dry patch down the bore. Run new patches down the bore until they come out clean.

    Once the patches are coming out completely clean, dip a new cleaning patch in oil and run it through the bore once. This lubricates the barrel and prevents rusting.

    Take a toothbrush and dip it in cleaning solvent. Scrub the internal parts of the P85 with solvent and wipe clean with a rag. Continue this process until the rag remains clean after wiping the internal parts.

    Apply a small amount of oil on all the internal moving parts to lubricate them and prevent rust accumulation. Reassemble your P85 and store it in a dry place.


    • It is best to clean a firearm on a good-sized and well lit work table. This prevents the loss of small parts from the disassembled firearm. Gun cleaning kits specifically made for your P85's 9mm caliber are likely the best to use. However, a general rule of thumb is that the largest patches that can be easily inserted into the barrel should be used for a more thorough cleaning.


    • Wash your hands very carefully after you finish cleaning any gun, as the solvents and chemicals used can be somewhat toxic.
