Cleaning a 3 cu ft V blender

Question: 
How would you clean a 3 cu ft V blender?


Answer:
I recommend using a 0.5% Solujet solution of 12 L to clean the 3 cu ft V blender followed by 2 rinses and then a 3rd sampling rinse.  You may wish to do riboflavin UV testing to assure complete coating of the blender with this volume of water (see pp 100 of the book). 


Use the calculator at http://www.alconox.com/calculator.html to review acceptable residue limits. I suggest you use conductivity to detect the Solujet if you have such a meter available to you. As requested, here is a price quote for Solujet effective Jan 1, 2011. 

  • 1 gal Solujet $58.80. weighs 12 lbs 
  • Case 4X1 gal Solujet for $181.00, weighs 47 lbs

Alconox Detergent Ingredients

Question: 
How do I find out the ingredients of Alconox cleaners?


Answer:
To find out the ingredients of Alconox cleaners, first review either the Pharmaceutical Cleaning Validation references, the MSDS or technical bulletin for the brand you are interested in.

The Pharmaceutical Cleaning Validation References discuss various analytical methods to detect components of the detergents along with general information about how much of the component of interest is in each detergent.   The MSDS discloses approximate content of various ingredients, including any ingredients with any particular associated hazard or irritation.

The technical bulletin gives a list of the general ingredient types in each product.  If further detail is required, you will need to contact Alconox at cleaning@alconox.com and ask for a non-disclosure agreement for the brand of cleaner you want to know the ingredients for along with the purpose for your need to receive this proprietary information disclosure.  Your request will be evaluated and an agreement sent if appropriate.
