Residual Chlorine on Printed Circuit Boards

Q. We have found chlorine present on our printed circuit boards after ultrasonic cleaning and distilled water rinse.  As ultrasonic cleaning detergent, we’re using either Liquinox or Detergent 8, but are unsure which one was used on affected boards.  Could either be contributing to this issue?

A. It’s highly unlikely that either detergent, or your cleaning process, is the source of the chlorine residue.  The cleaning process you described, if using detergent at recommended dilution levels, should successfully remove flux and process residues.

Detergent Color Variations

Q. The color of our Liquinox is slightly different by lot number. Why is this happening? Is there an issue, perhaps we have done something wrong with storage?

Cleaning in Food & Beverage Manufacturing: Does Liquinox Kill Bacteria?

Q. Will Liquinox kill and bacteria, yeast and molds in a nutritional food and beverage manufacturing facility? Has it been ISO 17025 lab and/or FDA approved or verified for this purpose?

A. Alconox, Inc. detergents remove pathogens, but they do not kill them, and none of the detergents from Alconox have sporicidal properties. We do speak, in our technical bulletin about how, “Liquinox,  in concentrated form, will not support bacterial growth,” but we say this as a….

Is Liquinox Drain Safe?

Q. In reviewing the SDS for Liquinox, we noticed that it says “Should not be released into the environment. Prevent from reaching drains, sewer or waterway.” How do you recommend we rinse components if Liquinox should not reach the drain?

A. The section you mention in the SDS for Liquinox® Critical Cleaning Liquid Detergent , 6.1, refers to untreated drains (i.e. the street) and other direct-to-environment pathways. The drains from labs, manufacturing plants and the like will have septic and/or treatment processes prior to the environment. In fact, we often…

Pharmaceutical Cleaning: Probiotics

Q: Can you tell me if Liquinox can clean/remove pharmaceutical probiotics? We use this product to clean our packaging lines. We have a customer who is looking to have us package their probiotic product.

A: Liquinox® Critical Cleaning Liquid Detergent is an excellent emulsifier of organic and oily residues. It will do the job. Best practice, however, would be to incorporate a powerful emulsifier of organic and oily residues, along with enhanced protein removal.

Ensuring Accurate Formulation of Liquinox Detergent

Q. I am a validation manager and we use Liquinox in multiple pieces of equipment across our manufacturing site. While witnessing our cleaning, I noticed the dilution instructions are not being followed. Instead, operators are adding some squirts/pumps/pours from the bottle into a bucket with purified water. Does Liquinox have a range of effective concentration?  Do you have auto-mix ideas or other dosing solutions for customers facing this issue of accurate formulation?
