Every couple of days rust stains appear on the deck
, below stanchion bases
They are ease to remove. I a few seconds with oxalic, phosphoric or citric, they dissappear. However, in a few days they come again.
It is obvious under the base(between the deck
and the stanchion base) there is corrosion
Unmounting is not an easy option.
-Is there a way to block these stains without to dissamble the stanchions?
-If not, what is the best treatment, besides cleanning, polishing and passivating, not to repeat these situation?
Thanks in advance!!!!
