Gerald, I've always been curious about this. How much more difficult is it to dissolve Metol in water without the "pinch" of sulfite that is usually recommended? I'm asking because I use a lot of Perceptol which comes in two parts. Part B lists Sodium Sulfite on the packet but I don't think there is any Sulfite in Part A, which is the Metol, and Part A seems to go into solution quite quickly/easily.
