Answer: Many of the Alconox brands including Alconox, Liquinox, Alcojet, Detojet, Detergent 8, Luminox, Solujet and Tergajet can be mixed with bleach hypochlorite for enhanced disinfection, bleaching or oxidizing properties. Alcojet and Detojet already contain an active chlorine compound. Tergajet already contains an active oxygen compound that gives peroxide oxidation performance. It may not be necessary to add hypochlorite to Alcojet, Detojet, or Tergajet. There are other Alconox brands whose cleaning ability is negatively impacted if bleach is added. For example, adding bleach to Tergazyme will denature the enzyme and render it inactive, in fact the enzyme in Tergazyme will be inactivated within seconds to exposure of 300 ppm hypochlorite, and within 2 minutes to exposure of 3.5 ppm hypochlorite at 100 deg F (37 deg C). Thus, it is not recommended to add bleach to Tergazyme. Citranox and Citrajet are acid cleaners and should not be mixed with hypochlorite because in sufficient quantities the mixture can form toxic chlorine gas, as they can acidify the bleach solution to below pH 7. It is not recommended to add hypochlorite to Citranox or Citrajet. Alcotabs, Tablet Pipet Detergent, is another brand that is negatively impacted by the high pH of most bleach solutions. Adding bleach to Alcotabs can cause the pH of the solution to rise above pH 7 and prevent the effervescent - bubbling action of Alcotabs. It is not recommended to add bleach to Alcotabs.
