Acid Cleaners

  • While alkaline cleaners are great for removing oils and heavy soils, they are not great for things like beer stone, water scale, and aluminum oxide.  This is where acid cleaners flourish.  Alkaline and acid cleaners are meant to be used in conjunction as part of a 2-part cleaning regimen for the most effective clean.
  • When using acid cleaners ensure that you are using the appropriate solution and blend for your equipment’s material.  Some acids work best at certain temperatures, so always make sure to check the usage guide for your chosen product.
  • A good cleaning product will work to remove organic soils on contact, without requiring laborious scrubbing.  When looking for a new product, take into account your manufacturing process, amount of leftover soils, and the equipment’s materials.
