Can my titanium camping dishes be washed in the dishwasher?

I have a (i believe) Snow Peak brand titanium bowl and a couple of spoons (REI TiWare Long handled spoon) that we generally use for camping. I can't find anything that indicates they are dishwasher safe, my packaging and labels are long gone on these items. Anyone know the Manufacturer recommend, or their own practical experience with putting titanium in a dishwasher?
