Removing scale buildup on stainless


I have a calcium silicate scale buildup on a machine made with a thin Stainless steel plate. Hard to access the scale, but can easily fill with liquid. Can I dissolve the scale and not damage the metal?

To remove water scale build up in stainless steel heating or cooling jackets(Calcium Carbonate)a 10% by weight solution of Sulfamic Acid circulated at ambient temperature, should do the trick. You may have to replace spent solutions a few times through the processing as the reaction depletes. Rinse well!

I think you can use ordinary vinegar.

Good luck!

Citric acid formulations work very well for this, also.
