Water Hardness and Alconox Texture
Q. We have had a customer call and say the product is not “sudsy & slimy” like it usually is.
A. Variations in normal water hardness will not impact the detergency of Alconox, but they can change the foam and feel of a solution. If the client has had any change in the hardness (amount of calcium and magnesium in the water) of their water used to make solutions, this can cause changes in the “slipperyness” and foaminess of the solution. Harder water will make less foam because the calcium and magnesium ions in the water form insoluble dodecylbenzene sulfonate soaps that must be dispersed and emulsified by the cleaner, thereby depleting available foam making ingredients.
Medical Device Cleaning – 303 SS Pins
Q. The 303 staiinless steel pins we are attempting to clean appears clean but the silicone adhesive Dow Corning 3-8264 does not consistently adhere to the pins. Is the Alcojet cleaner the correct cleaner to remove the maching oils from the pins and leave the surface residue free for bonding. I am looking for the proper cleaner to use to prepare some small parts for bonding. We are attempting to use silicone to seal 303 stainless steel pins into a black polycarbonate housing.
