Core cleaning for the assemblies acid would eat
Mixed-metal assemblies, soldered joints, sensitive substrates: plenty of cores need descaling and cannot survive pH 1 to get it. CoreKleen Pro descales at pH 6 — slower than the strong acid, and infinitely faster than the replacement core you did not have to buy.
It is the version for food-plant hardware with soft solder, instruments with mixed metallurgy, and any core where the customer's first question is 'is it safe on…'. The answer, unusually for descaling chemistry, is usually yes.
Pair patience with temperature — 40–60 °C and time do at pH 6 what violence does at pH 1.
Where it earns its keep
Scale removal on sensitive substrates and mixed-metal assemblies.
Dose: 10–30%. The trial sets your exact process values; the TDS governs.
