Even on carefully maintained stainless surfaces, undesirable coatings and deposits can form, especially in pharmaceutical, biotechnology and food production facilities. These deposits can impair surface quality, lead to particle contamination, promote the growth of biofilms and make cleaning more difficult. Various causes are identified in this context:

  • Contamination of water piping systems due to microbial contamination – the best known contamination is the formation of biofilms
  • Rouging
  • Blacking
  • Corrosion tensions
