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.
I use SM mostly on wood but if you’re curious I would do a small test area and see if it gets you the results you want. I usually downstream SH for metal buildings….dont think they had carbon on it though. Just rinse real well with metal though.
Downstreamed most of the job. Still on going. Got some rust removal in as well. Some of the tanks needed a higher percentage where the 12v came in handy.
