Hi All
In a recent job that we done, we use galvanized sheets that were stock in the supplier for several months.
with the ducting already installed we see white spots, like a powder. We ask the supplier and He says that is humidity, but someone told us that is in english called "white rusting".
the supplier sugested that we can use paraffin 0on the sheets to clean this white rust, but we have almost the total of the ducts on site and installed.
The question is: is there any product that we can apply to clean this white rust?
your help would be much appreciated
Thanks in advwence
