As a hobbiest, I do not have the same option such as a service that
changes out the parts washer solvent. I have a 20 gal parts washer
with with a electric pump and sprayer. In the past I have used paint
thinner as the solvent. A local paint supply store sold the thinner
in bulk (at $2/gal, the price was right) and the evaporation was not
too fast. Now I have to buy the paint thinner at retail.

At the other end, disposing of the dirty solvent poses a problem for
me. Lately, I have been thinking that if my solvent were say
kerosene or diesel (an oil) maybe I could dispose of the dirty solvent
with the used oil that my local autoparts accept for free. I do not
want to be the person that "contaminates" the used oil bin.

I have also been thinking of adding an engine oil filter between the
pump and the sprayer, not sure that the pump has enough power to push
the solvent thru a filter. If it works, I might not need to change
the solvent for many years.

My primary parts cleaner is a 55-gallon drum. It has a false floor about
12 inches down. Another 12 inches down is the pump.
I use kerosene or diesel oil.
The bottom 10-12" is water. The idea is that the heavier particles
settle into the water and keeps the solvent cleaner. Seems to work.


Be cafeful if the bottom of the drum rusts through.
Thank You,
Randy
