What should happen if oxidation has formed on the machine, including the solvent chamber walls/surfaces, piping, or the components themselves?
The machine should be shut down as soon as possible and serviced. The oxidated residue may contain acidic content that could damage the parts if the contact is sustained long enough. Many of the chemistry and machine companies have a longer procedure for when this happens to minimize the damage and clean the oxidation and prepare the surface so it’s unlikely to return.
