So what do you do with denatured alcohol?
According to a 1917 off print from Dyke's on the maintenance of the Ford, the alcohol is mixed with kerosene and poured into each cylinder when the engine is hot. Allowed to set over night to loosen up carbon in the head and pistons.
Recommended every 200 miles.
The alcohol was mixed with water and used as winter engine coolant. The “denatured “ was a version of ethyl alcohol that was undrinkable , so no “sin taxes” were charged. Ethyl alcohol is not hard on rubber hoses etc.
You are correct that Ethyl alcohol is not hard on rubber hoses (Jaguar used to recommend a every-three year brake system flush with Ethyl alcohol), but the same is not true of all synthetic rubber hoses. Ask me how I know...
Denatured alcohol has many uses. For example, it is the solvent in shellac. It is used in alcohol lamps and burners. I use it all the time for cleaning. I usually pick it up cheap at estate sales instead of paying full price at the hardware store.
The old pump looks a little like this one. I'll bet Charley S. could tell us more.
I shouldn't admit to using E-85 as a cleaning solvent. it dissolves oil, old oil and carbon. Used it to get grease off my rockys. I don't believe it is as flammable as gasoline, burning with a low blue flame. Cheaper than alcohol at the store.
they are bowser pumps cast iron in the old pic tin in richards pic. i have them all. charley
I Have a cheap plastic battery screw driver that the plastic case had started to degrade and became very sticky like I have seen other plastic bodied tools,cameras and other items do.
I took the screwdriver and gave it a about a dozen wipe downs with a rag soaked in alcohol and finally
the layers of sticky stuff started to dissolve and the tool is like new except it took the shine off the least of my problems.
