I've become a big fan of easy, convenient wipes for quickly maintaining my bags and getting them ready for storage. I started doing this after I took my mahagony XL ergo pleated hobo out for the fall season.
The bag looked fine when I stuffed it and put it in the dustbag the previous spring, but the next time I saw it, there were dirty marks, finger prints and other flaws visible. I was able to clean her up and make her look pretty again but it made me aware of the importance of cleaning, conditioning, and shining before storage.
The trouble is, I'm not always willing to drag out the cleaning, conditioning, and polishing supplies when I am switching bags. Now for most bags I use Lexol cleaning wipes, Lexol conditioning wipes, and Goddard's jewelry wipes to clean, condition, and shine. After treatment, I let the bag dry overnight and then stuff and bag it for storage.
I keep the stuffing in the dustbag for the bag I am currently carrying so I don't have to hunt around for packing materials.
I usually just wipe patent bags with a soft cloth and water and use the Goddard's wipes on the hardware.
Good luck!
