came across this ‘recipe’ for cleaning oils, dirt, etc. from jewelry
in one of my ancient reference issues of some gemstone publication
(from the 50s):
2 parts glycerin, 3 parts ammonia, 4 parts castor oil. mix all parts
in ‘roomy’ glass jar & close tightly until ready to use. soak
jewelry for one half (1/2) of an hour & WITHOUT rinsing, put into
another container of 1 part ammonia & 4 parts water. here it got
hazy about soaking time but i’d keep an eye on it for a few minutes,
if the piece hasn’t melted into a "kinetic, free flowing, energetic"
blob, remove & gently brush crevices with a baby’s hair brush, a
mushroom brush (what! no mushroom brush?? get thee to a kitchen
emporium!) or a water color paint brush - the only brushes i know
soft enough to not scratch metal. rinse. rinse. rinse. buff dry
and/or place on a towel spread on the floor in front of the
refrigerator (even some newer model refers can dry tennies overnight
if placed on side with top towards refer) suggestion: train other
inhabitants, biped or quadruped, to jump over spread towel.
good luck -
people - you’ve lives, use them, share them, take them seriously by
living with great humor.
