[https://jfoodprotection.org/doi/pdf/10.4315/0362-028X-60.1.43 Frank and Chimielewski] investigated the effectiveness of Quaternary Ammonium Compound or Chlorine on stainless steel and other domestic food preparation surfaces. The results indicate that different materials have an inherent different ability to be sanitised. Although the results indicated that abrasion (and therefore increasing surface roughness) does not always reduce the effectiveness of sanitising on clean surfaces, if adherent soil is not removed, microbial survival could be enhanced. Sanitation effectiveness is not simply a result of surface roughness or porosity.<ref name=cluett>https://ujcontent.uj.ac.za/vital/access/services/Download/uj:14727/CONTENT1</ref> | [https://jfoodprotection.org/doi/pdf/10.4315/0362-028X-60.1.43 Frank and Chimielewski] investigated the effectiveness of Quaternary Ammonium Compound or Chlorine on stainless steel and other domestic food preparation surfaces.

For organic soil, the best thing is warm/hot sodium hydroxide, 3-5% solution. Sure PBW is caustic (kinda) but is nothing compared to the power of lye, best of all it's way cheap. After that, rinse with a weak acid solution and you're sparkling shiny clean. NaOH does have a dark side though and if any gets on you, it will make soap out of the affected parts. Especially bad in the eyes.<ref>[http://www.themodernbrewhouse.com/forum/viewtopic.php?f=18&t=1535 "Proper kettle care."] Low Oxygen Brewing forum, 2020.</ref> | For organic soil, the best thing is warm/hot sodium hydroxide, 3-5% solution.
