ISOPROPYL ALCOHOL (IPA) is widely accepted as a good liquid for keeping cleanroom surfaces in pristine condition. But what about methyl, ethyl, or butyl alcohol? Why aren’t these types of alcohols considered for cleanroom cleaning, too? It all comes down to performance, safety, and price. Methyl Alcohol And Evaporation At room temperature, methyl alcohol has three [Read More…]
IF YOU ARE MANUFACTURING in an aseptic environment, it’s important for your cleanroom supplies to be sterilized with a validated process.

Bleach solutions, which are active against bacteria, viruses, [Read More…]
YOU CAN BUY SOLVENTS like acetone and turpentine from a hardware store, but you really shouldn’t. Solvents sold in the hardware store are not refined to the level required for cleanroom cleaning. When applied to surfaces, the hardware store variety of solvents will leave visible residues behind after they have evaporated. Cleaning With Acetone Or Turpentine [Read More…]
THOUGH PHENOLIC SOLUTIONS are often referred to as “cleaning solutions,” they actually deviate somewhat from the typical cleaning solution. Generally, cleaning solutions are characterized by their ability to remove soils (contaminants) from surfaces. Phenolic solutions don’t really do this. Cleaning solutions remove soils from surfaces by lowering the surface tension of the thin water layer that [Read More…]
CLEANROOM SOPs cover everything from gowning and hygiene to allowable materials and maintenance. An audit can ensure conformance to those standards.
