Rifle or handgun with a synthetic stock

Liquid abrasive cleanser (such as Soft Scrub)
Old toothbrush
Soft cloth
High-grade gun oil
Cleaning synthetic gun stocks should be a part of a seasonal maintenance of your guns. Grime and dirt can build up in the crevices of the gun stock and may create damage to the working mechanism of the gun. Corrosion can begin to form if left unchecked on a dirty gun. Regular cleaning can keep your guns in safe, effective working order.
Remove all ammunition before cleaning the firearm.
Remove the barrel and all mechanisms of the gun using the screwdriver. The liquid abrasive cleanser should not come in contact with any metal parts. If the cleaner does, you should oil the metal parts thoroughly and wipe clean with a soft cloth.
Brush out dirt with the old toothbrush before applying the liquid abrasive cleanser.
Squirt some of the liquid abrasive cleanser onto the stock. Using the toothbrush, rub the cleanser into the material in small circular strokes.
Clean one area at a time and then wipe the residue with the soft cloth. Do not allow the liquid abrasive cleanser to dry on the synthetic gun stock; the dried cleanser maybe more difficult to remove than the dirt and grime.
Clean the gun stock inside and out with the cleanser.
Pour a small amount of high-grade gun oil into a clean cloth and wipe the whole surface of the gun stock. This will help to remove any unseen cleanser residue from the synthetic gun stock.
Reassemble the metal parts into the gun stock. Be sure to give all hidden parts, concealed by the stock, a thorough wiping down with the high-grade oil. This will prevent corrosion from forming the unexposed parts.
