I think many of us arre overly concerned with the need to keep our guns cleaned. I have guns from the 49s, 50s, 60s, and 70s that were left uncleaned in a dry secure place for decades and they still look and perform like they were cleaned frequently. As long as they are stored dry and secure with a little oil on them, I don't think it matters much. I inherited 2 shotguns from a cousin who acquired them in car trades at his dealership. He didn't clean them but simply put them in a closet for several decades. One was made in 1948 and the other was made in 1950. When I got them about 13 or 14 years ago, I shot them to make sure they shot OK before I cleaned them lightly and put them back in storage.
