Maintenance you skip that you shouldn't

[Woodstash]

I never clean my magazines. I probably should but they keep working so I don't. What maintenance task do you skip even though you know you're supposed to do it?

I skip cleaning my mags too. They keep feeding fine, so it feels unnecessary, probably dumb though.

I have greatly reduced pistol and AR cleaning.

Mags get cleaned when they look bad.
