Although stainless steel is extremely durable, it can be damaged by exposure to chlorine – especially when submerged for an extended period of time, and repeatedly, in chlorinated water. Chlorine affects stainless steel because it breaks down what is known as the 'passive film' on the surface of stainless steel.
Considering this, can bleach corrode stainless steel?
Liquid bleach (sodium hypochlorite solution) is used as a disinfectant in pharmaceutical, bioprocessing, and medical device facilities commonly at a 1:10 dilution (one part bleach combined with nine parts water). However, bleach is known to be corrosive to metals and can cause damage to some plastics.
Can chlorine cause corrosion?
Further, adding chlorine to the finished water may make other metals in a system more likely to corrode. Adding free chlorine appears to affect iron the most. Chlorine also appears to have an effect on copper and lead, but it may or may not increase corrosion with these metals.
What will bleach do to stainless steel?
Abrasive cleaners will scratch the surface and should always be avoided. Bleach will stain and damage stainless steel. Do not use cleaning sprays or solutions that contain bleach. Dirty water and cleaning solutions can leave a residue that can stain and damage the surface, so don't forget to rinse and dry.
