Minimum Detergent Concentration?

My question is related to a minimum detergent concentration.  We manually wash labware of all sizes in 0.3% Liquinox solution. We also pre-wash or pre-rinse the labware and control our parts load.  We rarely have failures. We want to change our protocol to extend the wash water use for one day instead of based on a numerical parts load.  Do you think a 0.3% Liquinox concentration is sufficient detergent capacity to go an entire day?

How to Clean Mold Release Agent from HDPE parts?

Q. We are looking for a product that will allow us to clean mold release agent from the surface of molded HDPE parts. A. The best way to reliably remove silicone based mold release agents is to immerse the HDPE parts in very hot (170ºF) 2% Alconox detergent followed by a very hot (170ºF) rinse, ideally both in ultrasonic tanks. After the first very hot rinse, normal ambient temperature rinsing can be done. This can also be done with stiff brushes, but of course protective equipment must be worn.

The theory behind this is that …
