Residue Testing with pH Strips
Q. Can I use pH paper to confirm cleaning and rinsing of labware to comply with lab accreditation requirements?
A. If you are going to use pH strips to comply with lab accreditation requirements, you need to verify that your detergents are not interfering with the strips and papers. Detergents and surface active agents can interfere with some pH paper by causing a decrease of several pH units in reading. Please test any pH paper you intend to use …

Addition of Acid Rinse to Wash Cycle
We have a glass wash machine and use Alcojet for it. We would like to know if you need to include a neutralizing agent like Citrajet as part of the wash cycle (acid rinse)? Alcojet® Low Foaming Powdered Detergent is what we would call free-rinsing, meaning it rinses completely away with water without rinse aids.
Cleaning with Minimal Insect Toxicity
Q. We are looking for cleaners that are minimally toxic or non-toxic to insects while effectively cleaning and removing biological debris, sugar, and pathogens.
A. Thank you for your request for a detergent that is minimally or non-toxic to insects. We regret to inform you that we do not have insect toxicity studies for our detergents. The mammalian and systemic toxicity information that we do have, however, shows that Liquinox® is very low in toxicity.
