By their nature, and because of the job they do, base gaskets don't really respond much to being soaked... they're pretty resistant to most liquids!
I've always found that a new Stanley knife blade, held at the shallowest possible angle, is the best thing for gasket removal. The key is to take all the time in the world to scrape the stubborn gasket off carefully.
Just make sure the sharp edge is always in contact with as much of the gasket face as possible. You don't want any sharp corners digging in to the soft alloy.
I generally find there's not enough room to put the blade in a handle, and find I have much more control over it by hand anyway.
