No I really don't know. You would have to be careful it doesn't effect the material if your soaking it for a long time. Maybe fuel??
Best solvent for breaking down carbon
As the title says. Anyone know of a really good solvent for soaking valves (out of engine) in to remove the baked on carbon?

Caustic soda. You can buy the stuff from your local woolies etc (comes in a little plastic jar/bucket). Mix with water, put valves in, pull them out every so often and give a wash/scrub just to agitate the carbon to help it come off.
If you heat the solution it works even better.
WARNING: Wear eye protection, gloves, long sleeves, shoes, etc etc... Its' use (amongst other things) is dissolving bodies. You will know super quickly if you spill it on yourself (terrible itching, which if you don't wash off will result in terrible burning). Also, don't breath the shit in! Same deal as the above, but with your lungs..
Oh yeah, I've split the shit on my skin before. Burnt like hell!. Never knew you could use it for carbon though, i"ll give it a crack
Wire brush on a bench grinder, and go easy on them. If you are getting sparks then you're probably removing valve.
carby cleaner?

Carby cleaner is just a low strength caustic solution
But yeah, if you have a drill-press and a wire brush that'd also be good.
use an oven cleaner (foam) spray. I've rebuilt a few 2stroke motors and its the best stuff for cleaning the carbon off the power valves.
Subaru upper engine cleaner?
If it's available in Aust. Get it from the Subaru Dealership.
In Nz we use it in all the Mitsi GDI crap to remove the caked on carbon from the intakes.
