Here is the scenario.
We blended a 250lb materials, 25% is coconut sugar. I decided to wiped it down, sanitize and test the blender flap for tree nuts. Results came back negative. After the test, we will be blending another 250lb of the same materials minus the coconut sugar. Someone told me that I made a wrong decision by not doing wash-rinse-sanitize. I explained that we run for only approximately 3 hours, the blender is stainless steel, we wiped down and sanitized, it is visually clean and I tested it.
