Ultrapac is a specific chem for a specific job. Great for soot and blow marks/edges. Powerburst is a great all round chemical provided you rinse correctly. I rather like pureclean and i'm getting on much better with Nemesis for some reason. Cleansmart, Solutions & Amtech do some good liquid microsplitters and are well worth a try. Enz-All is excellent for restaurants. Can't help with the machine as I have not used one.
