Curious as to what everyone uses. We are currently using the dip tank mix that came with our CCI tank. Followed by 701 for the haze, and 858 degreasers. Dip tank was definitely one of our best buys in recent years.

I really like Easiway supra and also followed with 701

GemZyne.
Doesn't knock emulsion off your screen and into your tank depleting your chems if you forget and leave
a screen in too long.

Dip tank #1 has CCI IW-108 with air agitation bubbles for ink loosening / removal and Dip tank #2 has GemZyme as well. Stuff is cheap and works great.

Ink dip = CCI Envirosolv Ink Cleaner
Emulsion dip = CCI Gemzyne
Probably doesn't much matter which specific chems you use so long as you let each chem do it's main job- i.e., don't mix your emulsion remover with your ink cleaner.

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.

Air agitation bubbles? Is this a portable motor that keeps the chemicals moving?

Air line from compressor with holes punched in. We do this also thanks to Homer. Works great. just get as much ink of beforehand and time things so nothing is in too long.

Supra and 701, don't waste anymore time. That simple!

Thanks to past advice on these boards, Supra + 701. Easy, works.

We use FranMar's dip tank - One Step I think it's called. We like it; only got back into dip tanks again last year.
