Optical Cleaning — Silicon Diffraction Gratings
Q. Using Detojet detergent at high concentration is damaging the silicon diffraction gratings without cleaning it sufficiently. I have also tried the Luminox solution but it does not clean the surface adequately. Are there any products offered by Alconox, Inc.that are low foaming, so they can be used in the parts washer, that will effectively clean silicon without damaging it?
Cleaning Grinding Wheels
Q. Need help cleaning dried on surry from diamond grinding wheels.
We recommend using a warm 1% Alconox® solution (1.25 oz/gal or 10 g/L) followed by a thorough water rinse to clean off dried on slurry from diamond grinding wheels. Alconox® contains excellent wetting agents and particulate dispersants that will remove the dried on slurry.

Compatibility of Alconox with Neoprene
Q. We want to check on the chemical compatibility of Alconox cleaner with neoprene to determine if it will compromise the integrity and properties of our parts. I have been unable to find much chemical compatibility data for alconox exposure to neoprene online so I’m hoping you can provide some help.
Cleaning Copper Optical Molds
Q. The ammonia-peroxide solution (also known as Standard Clean 1 or SC1) is a very effective cleaner on our nickel optical molds, but we cannot use that cleaner on our new copper optical molds. The SC1 solution is very corrosive to copper. So we would like to find another cleaner that we could use for both copper and nickel parts. We are mostly removing machining fluid and particulates. Our parts have a very tight spec on particulates. We need to have essentially no particulates greater than 10 um, and this is inspected with a microscope. Obviously, the ammonia-peroxide solution is moderately dangerous to work with, and disposal is expensive. We go through at least 55 gallons per month of the ammonia-peroxide solution, it is quite a hassle.
Cleaning Aluminum 6061-T6
Q. We have a new product to clean small precision parts of aluminum 6061-T6 which have been trough heat-treating (surface oxide) and afterwards machined (cutting fluids). What Alocnox product do you recommend?
A. For manual, soak and immersion cleaning of the aluminum, we recommend using a warm or hot 2% Citranox (2.5 oz/gal or 20 mL/L) mild, citric acid based detergent followed by …
