For me, I tend to let things go for a good while, then suddenly undertake a major project of cleaning and organizing to the max, only to let it go for an extended period of time, and then have to do all over again.
Believe it or not, I know where everything is. My wife is a clean freak, but she stays away from my gun cabinet. Once a year I will take everything out and clean and organize as I put it back in the cabinet. This system works for me.
Finding just the right cabinet for your guns and accessories can be a challenge, but there are some really great cabinets and storage safes available on Amazon.
