Hi all,
I was asked to cleaning the exterior steel siding of an industrial building. They process fish oil, employee who gave me a tour figured it may be a carbon build up but with how easy it was to wipe off I feel it may be organic build up. Either way I believe I have a solution for it.
I just wanted to ask if anyone has ever mixed sodium metasilicate to use as a degreaser? I see a lot of popular degreasers use sodium metasilicate or sodium hydroxide. In this case I was thinking about batch mixing SM and surfactant to possibly spray on the metal siding and rinse of, if in fact it is a carbon deposit.
Just curious of everyone’s thoughts. I have degreasers from a local chem company but this is a very large building and was thinking if possible it could be a big time cost saver.
The last picture uploaded is where I whipped off a bit of the build up.
