How can Cosmoline ruin your SKS?

Cosmoline is a substance that is used to protect firearms from rust and corrosion. It is a petroleum-based product that is applied to the metal surfaces of firearms before they are shipped. Cosmoline is a waxy, oily substance that is difficult to remove once it has been applied. If not removed properly, cosmoline can cause problems with the function of your firearm. It can gum up the works, making it difficult to operate the action. Cosmoline can also seep into the wood of your gun, causing the finish to become sticky and difficult to clean. If you are not careful, cosmoline can permanently damage your firearm.
The importance of cleanliness?
Cleaning cosmoline off of an SKS is important for several reasons. First, cosmoline is a corrosive substance that can damage the metal on the gun. Second, it can make the gun difficult to operate and can cause problems with the ammunition. Finally, cosmoline can be toxic if it is ingested, so it is important to make sure that it is removed from the gun before it is used.
The best way to clean cosmoline off of an SKS is to use a solvent that is designed for removing cosmoline. There are several solvents on the market that will do the job, but the best one to use is called CLP. CLP stands for “cleaning, lubricating, and protecting” and it does an excellent job of removing cosmoline.
To use CLP, simply apply it to a clean rag and wipe down the entire gun. Be sure to pay attention to any areas where cosmoline has built up, such as in the crevices around the trigger or in the magazine well. Once the gun is completely coated with CLP, let it sit for a few minutes to allow the solvent to work.
After a few minutes, take another clean rag and wipe down the gun again. This time, you should see the cosmoline coming off of the gun. If there are still some stubborn areas, you can use a toothbrush or other small brush to scrub them clean.
Once the gun is free of cosmoline, you can proceed with cleaning it in the usual way. Be sure to lubricate it well before you put it away, as cosmoline can damage the metal if it is left on for too long.
