For maximum solubility of the neutralized calcium (so that it can be
rinsed away readily), nitric (1 or 2%) and hydrochloric (2%) acids are
indicated. I have found that citric acid is good enough in this regard,
although the solubility of calcium citrate is little more than
"slightly soluble," so it presumably requires a more thorough rinse.
