If moisture builds up on the glass or window frame when the winsert is installed, remove the winsert and wipe the moisture away so that mold does not form.
To store winserts when the winter is over, stack them carefully and protect them behind a solid surface, if possible, to reduce the risk of the plastic being punctured. We anticipate that with careful handling, winserts should last for several winters. Small tears in the plastic can be
repaired with clear tape.
