"The proper and safest way to clean and store a firearm is to first make sure that there is no ammunition in any part of the firearm. Take it to a gun smith to have it properly cleaned and when you pick it up, they can sell you a trigger lock for your gun. Always store your gun in a lock box."

When possible, clean from the chamber to the muzzle. Due to the design of some firearms, this may be difficult or impossible. Cleaning in that fashion will push fouling/ carbon OUT of the gun, away from the working parts.
Fail to clean and maintain a firearm that is exposed to weather, and eventually rust and corrosion will make the gun unable or unsafe to fire.
Firearms should be cleaned after every use to ensure optimal performance and longevity. If a firearm has been stored for an extended period without use, it’s advisable to clean it before using it again. Regular maintenance, even without recent use, can help prevent rust and corrosion. Additionally, checking and cleaning your firearm periodically can enhance safety and reliability.
It is generally recommended to have no ammunition present when cleaning or preparing to clean a firearm to ensure maximum safety. If ammunition must be nearby, ensure it is stored securely and out of reach, and always follow the basic safety rules: treat every firearm as if it is loaded, keep the muzzle pointed in a safe direction, and engage the safety mechanism if applicable. Always double-check that the firearm is unloaded before beginning any cleaning procedures. Safety should always be the top priority.

You should never store a dirty firearm. They should be cleaned after every use, especially if you're firing ammunition with corrosive primers. It's not absolute necessity that you clean them every single time - and many people don't - but it's good practice, especially for a firearm which you may be using to defend yourself with.
