Big D Water Soluble Deodorant is concentrated, easy to use and effective. Just a small amount added to water or other cleaning products will destroy odors on contact without changing the properties of the cleaner. Big D deodorants actually eliminate odors...not just mask them. And they are safe - nontoxic, nonflammable, biodegradable, will not stain any material unaffected by plain water and are USDA approved. Water Soluble Deodorant is versatile. Use it for mopping, shampooing, rinsing or in a hand sprayer or fogger.
