Cleaning and passivating 316 stainless cables near the ocean using Naval Jelly?
A 40 year old hotel in Hawaii recently completed a major renovation. Part of the renovation included the addition of horizontal stainless steel cable railings and vertical pickets using the same material. The cable and billets began to show rust within the first few months after installation. The engineering department is looking for a reasonably simple method to a. remove the surface rust and b. encourage passivation layer.

Naval jelly is a poor man's phosphate and it does not work well on stainless. Cable is extremely difficult to get rust out.
Consider paint.

Cleaning from rust and passivating (or passivating only) can be done by special gels. The thickness of such gels can be varied depending on climate. also various compositions can be adjusted depending on stainless steel alloy type and environment.
We do not sell gels retail. But if any shop want to mix their own gels in-house - contact us for more information and conditions.
