I have become a very big proponent of knowing what you are using.
So:
Look at the SDS sheets for the emulsion remover you want to use. Find its % of periodic acid - this is the better ingredient that breaks down emulsion and the one you want to use. Over 8% and it ships ORMD. ~ over 23% is hazmat. You can quickly have a sense by how it ships. Some vendors will know what it is.
When you put it into a 30 gallon dip tank, you want your final mixed percentage to be about .75% to .85% periodic acid for best results. You can run hotter if you want though.
Next thing to look at are the surfactants in the solution. Make sure that they are not harmful to aquatic wildlife. Many surfactants used are iffy. Those are the ingredients that help with cleaning the mesh and penetration into the emulsion (some). They are not truly needed, but are very helpful.
So, beyond that, lots of stuff will work. Know the tools you have chosen.
And like Chris said, dont mix cleaners and stencil removers - if you do, only mix whats needed immediately, like you would with discharge ink.
