I use either oven cleaner, or lacquer thinner where I immerse the blade and put it in a covered, sealed container.
If I use oven cleaner, I have to wash the blade off and rinse away the oven cleaner, sometimes a nasty task. My lacquer thinner I simply get a funnel and put it back in its original can, to be used again. Any debris from the blade floats to the bottom of the can and I never see it.
