Cleaning Semiconductor Equipment

Q. We’re getting some residue from foaming of detergent on our semiconductor handling equipment.
A. To clean semiconductor handling equipment in electronics, use a warm 3% Detergent 8 (30 mL/L) solution followed by a deionized water rinse to clean the equipment. Detergent 8 is free of any metal ion ingredients such as sodium that can dope a semiconductor.

Cleaning Mild Tool Steel

Q. How to clean mild tool steel tablet press punches and dies?
A. Mild tool steel, sometimes called S7, will flash rush during rinsing, particularly if you rinse with hot water. All the cleaners that have good chelating agents (all but Luminox and Detergent 8) can safely clean tool steel because the chelating agents tie up the iron oxide and do not let it auto-catalytically expand and form rust.

Cleaning Electronic Parts for High-Voltage Applications

Q. How can I clean electronic parts and assemblies for extremely high-resistance and/or high-voltage applications?

A. I recommend you clean with the product Detergent 8. Detergent 8 is an ion-free cleaner that cannot leave a conductive detergent residue. You use Detergent 8 at a 2-5% dilution (2.5 oz/gal to 6.5 oz/gal) depending on how you are using it. For soaking use 5%, for ultrasonic tanks use 3% and for pressure spray washing use 2%. Rinse thoroughly with deionized water after cleaning.

Lab Glassware

Cleaning Glassware with Adhesives and APIs

Q. We have glassware that contains adhesive and API dissolved in organic solvents. If we do not do additional organic rinses prior to the aqueous rinses we have issues. Is there any way we can avoid the organic rinses?
A. To avoid organic rinses, you can soak in a high emulsifying cleaner such as a 1% Alconox solution (1.25 oz/gal or 10 g/L) prior to aqueous rinsing. Ideally soak in a warm or hot solution for fastest and most reliable results. The emulsifiers in Alconox will emulsify the solvents and active pharmaceutical ingredients (API). Be sure to rinse at the same temperature you are soaking at so you do not break the emulsion and redeposit the API or solvents. If you soak hot . . .

Bleach with Detergents for Disinfection?

Adding bleach to Alconox and Liquinox detergents can be done to enhance the disinfecting and oxidizing properties of these cleaners. Adding oxidizing does bring one more cleaning mechanism to the cleaning process which can be helpful if you are trying to clean dyes, pigments, heavy burned on organic residues and other residues that are labile to oxidation. You can get some disinfection, but as we will explain, you need to clean a surface first before you disinfect.

Cleaning Aluminum without Corrosion

Q. How is galvanic corrosion prevented when cleaning aluminum?

A. Aluminum is an active metal that is somewhat high on the “anodic index” of the galvanic series. If aluminum is cleaned with other metals present, you can create a battery and get galvanic corrosion. Aluminum should not be cleaned in the presence of metals that are significantly higher or lower on the anodic series; higher on the anodic scale such as zinc, magnesium or beryllium metals and lower on the anodic scale such as tin, brass, bronze, copper, silver, nickel and rhodium.

Cleaning Aluminum with Alconox

Q. Which Alconox cleaners can be used on Aluminum?

A. The Alconox brand cleaners recommended for cleaning aluminum are Alconox, Liquinox, Tergazyme, Alcojet, Alcotabs, Detojet, Citranox, Luminox, Citrajet, Solujet and Tergajet. Detergent 8 is not recommended for cleaning aluminum. Aluminum forms a natural passive layer in air that allows it to be successfully cleaned without adverse reactions with cleaner. A passive layer forms in under an hour, provided there is no oily film present. Once the passive layer is formed, the recommended Alconox brand cleaners can be used to clean the aluminum at concentrations of less than 5% at 90 deg C or less for up to one hour.
