Sulphur hydroxide does not exists. There is a compound H2SO2 (formally S(OH)2), but it is an unstable acid known only as diluted orange-yellow water solution. This acid is called hyposulphurous acid.

SO2 + H2O ==> H2SO3
then
tends toward dilute sulfuric acid
or compounds with ions.
What will happen, especially if the system operates, is any sulfur and thus dioxide will react with the steam until there is some fluid usually a trend toward sulfuric acid highly diluted
and then when the system is switched down (cools) any residuals will reform and adhere films of slight acid which concentrate during evaporation and parts of sulfur, the pitting may be due to the steam, the sulfur just utilizes this as a location point as there is a hollow and grip surface where the system cannot rub it off. The sulfur water relationships require much equation arrangement with other compounds available, iron is a good one and you end up with H2S and varied gaseous extremes. Obviously it can just burn off, not good for your equipment over a long period of time. In theory lubricating fluids if feasible should clear such residues, in practice they may not and may be difficult to run with the equipment, some of those can lead to fires in unsuitable circumstances. Be careful of the combination of fluid products resulting. You may have seen fire start on lathe and metal swarf start to burn in both School, Technical College and industrial sites, smoke and everybody has to leave. Architects do not like steel, it expands concrete and the whole system will burn in high grade tube, tower fires, chimney heat as well as warp; all residues engineer’s oil rag and wastes and left over substances in buildings may catch alight in a fire damage and add to fire brigade (battalion) nightmares. Kings Cross underground. Sulfur substances are common migrated accumulated growths in waste materials, chemicals form by migration, hence igneous rocks. Wear and tear on surfaces may mean the equipment needs renewal, this can get much worse with time and no action. My understanding not having taken technology onward but from physical biological chemistry and physics is that sulfur related damage as you can observe may be severe. You may have steam pitting, the sulfur just uses this as adherence, that helps none in the wear of your equipment, on fine surfaces and particular materials it will rot the pits.
You are dealing with something at the opposite end to Tundra freeze thaw, hot cold similar to a Tropical forest but working much faster and soils will shift forest materials in accumulative rapid exchanges, the equipment you build/ operate is after all a soil rock derivative and OH and O are its main exchange activities.

Best wishes, the tech people will answer your resolution as best practice, in soils we keep away from sulfur sites obviously.
