Rogue 2 and Fury 3 deep cleaning

Just curious, how often do folks give these a deep clean as far as cleaning the o ring etc, and not just the quick brush off after every session? The manual says once a week so wanted to see if that’s what everyone’s doing. I’m gifting a Fury 3 to a friend who knows nothing about dhvs so want to give the right info. Any other tips and tricks to help them get started on the device would also be appreciated? As it’s their first one I opted for one of the more lightweight, easier vapes to maintain so fingers crossed.
