screenprinting chemical question

Hi all,
     In screenprinting there is an expensive chemical stuff called auto haze
that removes crud from screens. I noticed today it has potassium hydroxide
in it, in a paste base. Has anyone substituted another chemical for this
stuff in screenprinting that works as well and is not expensive? Isn't Red
Devil Lye 100% sodium hydroxide, and are the two (potassium and sodium
hydroxide) interchangeable to an extent, those of you chemists out there who
are not screenprinters per se?
