Hey SlickFloss - thanks for your reply. We have a strahman hose that sprays steam. Don't have a ton of scale, so that's good. With the soil in the kettle, we mostly spray wash with water to get big soil off (spray balls in the fermenters and kettle) or power washing for the really heavy soil in the kettle after stripping runs, so manual cleaning. Then citric acid wash in the kettle and caustic/citric/rinse in everything else.
Since we have the steam hose, I was wondering if that would be a good alternative, and perhaps sanitization method (for the bright tank we just got). However, from what I understand, this steam is "wet" steam and doesn't really get hot enough to do the sanitizing job, like "dry" steam.
But if I were to use it, how you use it, what is your method (if you don't mind my asking)? Do you attach it to, say, the drain, and fill up the vessel? To what temperature? How do you know if it has done the job of cleaning?
All our vessels are 4k litre (about 1k gallons). I am also going to look into aqueous ozone!
Again, thanks for your help.
