It’s only natural that contamination control in today’s world of critical environments is in a constant state of evolution. After all, the complexities of facilities and processes flow from the increasing intricacies of end products. And throughout the continued development of environmental monitoring programs, it pays dividends to recognize that what works today may not be the best solution for the future.
wiping is a cornerstone of contamination control. A liquid’s ability to
penetrate and sanitize the nooks and crannies of a surface—coupled with
a process-appropriate sorptive material for absorption—will remain
crucial to critical environments across industries.
Alcohol is a
lasting standard for wet wiping. While it doesn’t have the broadest kill
spectrum or the highest surface penetration, it is a gentle yet
effective sanitizer and reliable dissolver of ionic compounds and common
organics. Alcohol also evaporates cleanly enough to be used as a
residue remover for many other cleaning chemicals. Pairing alcohol—often
in a 70% IPA/30% USP purified DI water mixture—with a knitted polyester
or polyester-cellulose wipe has been a reliable choice for wide-ranging
critical cleaning applications.
It’s necessary to consider that
the process you designed two years ago may not be effective two years
from now. If this transpires, will your current supplier be able to meet
unanticipated process needs? While it’s important to recognize the
potential costs of product evaluation and risks associated with changing
suppliers, assessing your supplier’s innovative and evolving
capabilities is an equally important consideration.
