sprue screw/hinge I use a needle tip dropper bottle, with boolits still in the mold. I swivel the sprue plate seeing where the movement is in the washers and put a tiny drop there, then I swivel the sprue plate multiple times and wipe and oil (creep) I see [Do this every 1/2 pot full]
with synthetic 2 stroke oil/fuel additive
the cavities get a good scrubbing with dawn, hot water and a denture brush, dried then the mold get heated to 400° on a hot plate.
if boolits hang up after a few casts I rub the edges of the cavity (s) with the bottom of a carpenter pencil to remove any burs
if after a few casts the boolits aren't smooth and the alloy is up to 720° with tin in it I'll lightly smoke the cavities with a butane lighter
in worse case scenarios I lightly Leement (polish) the mold cavities (search leementing)
