Cleanroom wiping product
Wipes are widely used in almost every type of organization and sector for a huge array of cleaning tasks. In fact, they are so widely used that it is easy to take them for granted and to treat them as little more than a throw-away commodity.
Technicians and operators cannot do their jobs without the right tools and wipes are simply one of those tools. There are a number of different types on the market, but is one wipe the same as any other wipe?
In general, there are three broad categories of wiping products: non-woven wipes; woven or knitted wipes; and swabs. The cleaning surfaces are made from paper, cloth or synthetic materials, so which is the optimal product for a particular job?
The best place to start is by looking at absorbency of the contamination, then selecting further based on the cleanliness (lint and particulate) requirement.
Absorption usually is expressed in milliliters of water (or alcohol) absorbed by 1m2 of the material. But whereas some wipes work well with solvents or lacquers, they will not absorb water. For example, polyester is petroleum-based so polyester wipes are able to absorb gasoline, oils or grease easily. Cellulose wipes, on the other hand, are good for water-based contamination.
Cleanliness of the wipe is also crucial to the end result, and is measured in particles per square metre.
Cleanliness is inversely related to absorbency. The cleanest wipes may be less porous and unable to absorb as much, while more absorbent materials may leave fibres or residues.
Packaging also deserves some scrutiny. It should be free of particulate, with no fibres, plasticisers, silicones or ionics.
