Toluene (aka toluol) is a solvent for luster, I use it for cleaning my lust=
er brushes. It is not available in all States, it has been taken off the sh=
elves in Illinois, I purchased my last gallon in Iowa about 2-3 years ago. =
You can check your local hardware stores for availability. Toluene is a tox=
ic substance,
non-carcinogenic, but will get you loaded by inhalation -much as gin or whi=
skey by drinking; do not think of drinking toluene...
Luster essence is relatively expensive material for cleaning brushes
Hanovia (Englehard) used to sell something called brush cleaner, but Engleh=
ard has sold off it's Hanovia (hobby) division to Rusche and Rusche has als=
o messed with the products and I don't know what is available from them.I u=
se toluene by putting some into two 4-6 oz bottles or jars with screw lids;=
these are numbered #1 and #2. When done lustering I squeeze excess luster =
out of my brush with a paper towel then dip the brush into #1 and back out =
and brush the bristles out onto a paper towel. I do that 4-8 times then rep=
eat in #2 until the brush shows little evidence of luster color. After a wh=
ile the level of #1 drops and it starts to take on the color of lusters (tu=
rns brownish); I then dispose of #1, relabel #2 as #1 and put clean toluene=
into the old #1 (now #2)... I discovered toluene at a ceramic symposium in=
the Czech Republic, the decorators were using it to thin gold luster to br=
ushing consistency; and also for cleaning their brushes. I think
just about any solvent that is compatible with oil based materials, lacque=
r thinner, acetone, mineral spirits, turpentine, etc., would work for clean=
ing brushes. However I would only use essence or toluene for thinning luste=
rs; lusters are very complex chemically and I would not want to interfere w=
ith the properties given to them at their manufacture... There are two type=
s of essences for thinning luster, one for the common colors (Lustre Essenc=
e) and another for the Liquid Brights (Gold Essence). -Rimas

My neighbour who sells furnace oil puts his paint brushes used for painting
houses with oil paints in the furnace oil he sells, I have never seen dirty
paint brushes look so good after a few days in that oil.
It is known that some chemicals not sold as solvents dissolve other
chemicals.
It is a matter of difference in polarity, so told me a chemist with a PhD i=
n
chromatography.
