Things You'll Need
Instructions
Hold the nest carefully as the papery shell may easily be damaged by too much pressure from your hands.
Dampen a paper towel and wring out thoroughly; you don't want to get the nest wet as water may deteriorate the papery material the wasps made.
Wipe the stem lightly with the barely damp paper towel.
Dampen a cotton swab and use it for areas of the stem that may be protected by the rest of the nest.
