Good Solvent for cleaning exhaust/intake valves???

[bblockb]

Anyone familiar with a good solvent to use for cleaning up exhaust and intake valves (valves removed from Cyllinder head)

[terrible one]

I use a mix of kerosene and mineral spirits.

I've always used  the cheapest automotive paint thinner (gun wash) and then clean up the valve with a wire wheel attachment on a bench grinder,avoiding the top 2 thirds of the stem, and the valve seatting surface . hope this helps.

brake-fluid will do perfect.

a can of carb cleaner works great
