Non- toxic oxygen Cleaner Cleaning products with chlorine bleach and disinfecting ingredients leave residues that are persistent on surfaces, and in the air.  This creates the risk of ingestion by children and others who may touch or eat food from surfaces which were cleaned even hours earlier. Natural, oxygen-safe hydrogen peroxide is excellent alternative to chlorine bleach and toxic house hold cleaners. "Biodegradable"  means that a product breaks down into water, carbon dioxide and minerals, and is harmless to the environment.  Just about everything is biodegradable.  What is important, is the amount of time a compound takes to degrade, and if it is harmless during the process.  But be warned that "biodegradable," also appears on conventional products.  Hydrogen peroxide is composed of water and oxygen only. Hydrogen peroxide is considered the safest, all-natural effective sanitizer.  It kills micro organisms  by oxidizing them, which can best be described as a controlled burning process.  When hydrogen peroxide reacts with organic material, it breaks down into oxygen and water. One gallon (64 oz) of 35% tech grade hydrogen peroxide contains enough for up to 128  quarts  of all purpose cleaner and disinfectant. Tech Grade Peroxides are not the same. Our Tech Grade Hydrogen Peroxide differs slightly in that tap water is used in the production.  Only phosphorus is added to help neutralize the effects of chlorine. This allows tech grade peroxide to be produced for a lower cost then Food Grade. Our  Tech Grade Hydrogen Peroxide is to be used in bulk to sterilize and disinfect pools and spas.  For more information on hydrogen peroxide click here. Note: Tech Grade Hydrogen Peroxide is not for internal use.
