Using Acid to Clean Filters

Well last week we used an acid to clean a cartridge filter.  I thought this was a very weird occurrence.  I have spoken about the importance of chemistry in our business.  I learned something new last week when we used this acid.  I have also tried to communicate the importance of a team that can think outside the box. 
This week is a good example.  We have a filter bag that I am not happy with the results after cleaning the filter.    The filter bag has good air flow but seems stiffer that what it should be.  After communicating with the customer we found that this is a caramel coating is put on dog food to sweeten the food, and add coloring.
We used the food based acid to clean the filter bag.  It worked!
