Northernbrewer says it is a no-rinse cleanser. Personally, I wouldn't trust a no-rinse cleanser. Is it supposed to be a 2in1 Cleanser/Sanitizer? I've always heard to not use the 2in1 products. You want 2 steps..cleaning (then rinsing) then sanitizing. I always use PBW for cleaning, then rinse everything, and sanitize in StarSan. StarSan is a no-rinse acid-based sanitizer. Works great. I have experience with IoSan as well, but I prefer StarSan, as the iodine based sanitizers can really stain plastic equipment.
