How to clean and passivate new stainless steel equipment

New stainless steel equipment may have residual manufacturing oils, the best cleaner to remove these is Trisodium Phosphate but dish soap is a reasonable 2nd choice if you have none available.

Passivating stainless steel builds up the Chromium Oxide layer which prevents rusting to so that you can wash the metal with a 10ml/L solution of Chemsan or a 50g/L solution of Citric Acid crystals.
