I assume by "no-clean", you are using this synonymously with
"low-solids". IMHO, SG is not the correct way of measuring solids
content with low-solids. A little water in an alcohol-based one, for any
reason (and it happens) and you are up the greasy pole. In a water-based
one, SG is totally meaningless, as there is almost no difference between
the solvent and the solute. Consult your supplier for their
recommendations. Better still, use a spray fluxer that uses only virgin
flux, straight from the can, so that you have no maintenance to do.
