In the old days lenses came with cases.  Today except for the very
expensive L lenses Canon's EF lenses come without cases.  I have a
Canon bag DG100.  I keep the lenses and Digital Rebel body in the bag
when not in use.  The lenses and body are only protected by the Velcro
partitions in the DG bag.  

The equipment includes the following EF lenses:18-55 S lens, 28-135 IS
lens, 75-300 IS lens and a 100 Macro lens and finally the Camera body.

How are you guys keeping the equipment clean when stored.  Suggestions
appreciated.

Thanks,
