Here's a one pound box of the pure stuff- - - -with free shipping. It's the same degreaser I use, mixed about half a pound to 3 gallons of water, to hot clean firearms prior to bluing. Dissolve it in 180-200 degree water, and pour the block full of the solution. You can drain and reheat it if necessary.
