Opening a jar beats opening a window for odor control.

Nothing works better to remove persistent odors in the air than Fresh Wave® Crystal Gel. Just open a jar to deodorize any room or area – such as a basement or bathroom. Then allow ambient airflow to activate the unscented odor control gel for the whole room.
Quickly, effectively and without the use of perfumes or masking agents, Fresh Wave Crystal Gel eliminates odors including must, smoke and fish. And the Fresh Wave Crystal Gel product works around the clock, for approximately 60 to 90 days depending on conditions.
