How To Clean an Aluminum Coated Mirror

Q: We are looking to clean an aluminum coated mirror with a neutral, mild effective cleaner.  What can Alconox Inc. recommend?
A:  Typical residues found in laboratory, aerospace and optics industry mirror applications are adhered dust, dirt and water spots.  Occasionally oil spots and coolant residues will be found as well.

Defining Free Rinsing Detergent

A non-free rinsing cleaner might contain fragrances that were designed to deposit and leave a fresh scent, or it might contain corrosion inhibitors that are designed to deposit and leave behind an anti-corrosion film.

Alconox, Inc, cleaners are free rinsing detergents and do not leave deposits on substrates after rinsing.

Medical Device Cleaning: Soft Acrylic Intraocular Lenses (IOLs)

Q: We are cleaning both hydrophilic and hydrophobic acrylic polymers. The cleaning process we use is mostly manual, involves no extended soaking, rather short contact with rubbing, and/or usage in an ultrasonic bath. Which of your products — Alconox, Tergazyme or Liquinox — would be most suitable for the cleaning of soft acrylic intraocular lenses (IOLs)?

Ultrasonic Cleaning of Optical Devices

Q. Ultrasonic and forced DI water are not removing particles from the optical devices. We suspect that the particles are charged and that is playing a role in the difficulty of removing them. Rusting isn’t a problem but oxidation might be. Al, Ti are metals in the devices we use. The cleaning is followed by chemical etching so this can be an issue.

Clean Fingerprints off Optics with Ground Glass Barrels

Q. We are trying to clean fingerprints off optics with ground glass barrels. Liquinox® does not get the fingerprints off of the glass entirely. Why is that? What would you recommend instead and are your detergents safe for cleaning dielectrically coated optics?

Cleaning Fiber Optics

There is near zero tolerance of contamination in fiber optics. Fiber optic cable needs scrupulously clean surfaces at the glass joint to assure efficient light transmission. Any cleaner which leaves a residue will make matter worse as this will attract contaminants.
The best process for cleaning fiber optic cable is…..

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 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.

Optical Lens Cleaning

Q. How do you clean wax marks on optical lenses which are difficult to remove?
A. Use either 1% Alconox or Liquinox in a heated 160 deg F ultrasonic bath followed by a deionized water rinse to clean optical lenses during manufacturing.
