TRJ recommended Mirvac use the TIG Brush Weld Cleaning System to remove the rust and to passivate the affected areas. Ensitech were able to prove that by using the TIG Brush electrolytic weld cleaner with the correct fluids, onsite maintenance would restore the condition of stainless steel surfaces in a fast, safe, and cost effective manner unlike the use of pickling paste or abrasives.
After submitting the NSF approved safety data sheets (SDS), industry authoritative passivation reports, and explaining they were able to neutralise the fluids on site with minimal excess, Mirvac gave the green light for the repair to commence.
