Butyric acid, also known as butter acid or valeric acid, is a chemical that has an odor smell of vomit. Ozone and thermo fogging will not remove the odor. Butyric acid may be used in vandalism situations, such as attacks on abortion clinics or vehicle vandalism. This chemical is usually injected through convertible tops of vehicles to introduce the odor, or it is introduced into ventilation systems of buildings, doors, windows, etc.
When all other efforts have failed, turn to Last Resort. Powerful solvents and deodorants help destroy the most severe odors, including putrefaction, skunk odors and more.
Liqui-Zone performs in similar manner as ozone generating equipment except in chemical form to convert odors into harmless carbon dioxide and water vapors. It's most effective on dead body odors, skunk odors, charred wood, etc.
