Cleaning Salicylic Acid

Question:
What can be used to manually clean lotions, creames, emulsions containing salicylic acid from manufacturing equipment?

Answer:
In general salicylic acid is best cleaned by sodium phosphate or alkali citrate salt containing cleaners. Creams and lotions are often best cleaned by high alkaline cleaners. Alconox powder is moderately alkaline sodium phosphate containing cleaner that is somewhat safer for manual use than some high alkaline cleaners. Alconox is a powder and some companies may much prefer a liquid. Alconox would work well here and would be better than Liquinox for this application. If the customer prefers a liquid, I would recommend either Detojet or Solujet. Note that Detojet and Solujet are both hazardous corrosive liquids that require skin and eye protection for handling. Solujet and Detojet must ship on non-passenger aircraft and can only be air shipped in the 5 gallon (19 L) size.
