MOMS - Mold Odor Mildew Smoke - eliminates odors that can be oxidized. What can be oxidized? Mold, mildew, smoke smell from fire or tobacco, dust mite matter, mothball odor, curry and tough cooking odors embedded into a kitchen, allergens, dog and cat dander, viruses, germs and other funky odors. As MOMS works it smells a little like chlorine EXCEPT it is safer and more effective than chlorine. MOMS/Chlorine Dioxide/Clo2 is chlorine with an additional oxygen molecule added to its chemical structure. Extra oxygen is what makes it safer and more effective. MOMS puts a safe and invisible gas into a 2-liter container of cold water. It becomes a concentrate that you add more water too and spray specific areas that contain the offending odor. MOMS is great for spraying uneven surfaces like a stucco surface, carpet or siding affected by mold, mildew, smoke, viruses, any place you can visibly see mold or water or know they could become infected. Such as a carpet after flooding, light switch plates and door knobs in flu season, visible mold on furniture, etc. The 5 gram packet of MOMS will make up to ten 2-liter bottles of MOMS from the concentrate.
