If the budget will allow, buy a Loricraft. Not only is it far quieter, it does a better job (though at the cost of being slower).
Steaming is not a substitute for vacuuming. Heating the fluid in the grooves may (depending on the fluid) help it dislodge contaminants. But unless you remove the now scummy fluid from the grooves before it can evaporate, suspended contaminants will end up right back where they started. No towelling with any sort of microfiber cloth removes a fluid layer from a surface better than a focused, high velocity air stream, which is what RCM's (especially string types) provide.
