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 …
Cleaning Laboratory Glassware by Soaking
Q. Some of our glassware was left soaking in Alconox or Alconox and then bleach for a long period of time. Is this okay? A. Laboratory glassware that is completely submerged in an Alconox® solution is generally ok even with extended soaking. However, if you leave the laboratory glassware partially submerged…
Removing Trace Metals, Inorganics & Organics without Acid?
Q. We are trying to reanalyze our cleaning procedure. Do you have a product that removes trace metals, inorganics and organics without an additional acid rinse? We sample waste water influent and effluent and collect in plastic containers. Please let me know what you would recommend.
A. Organic residues are typically effectively removed by alkaline cleaning. The most robust way to remove trace metals and inorganics is to use an acid rinse. However . . .
Cleaning Space Environment Simulation Chambers
Q. We are currently using Alconox® for cleaning of space environment simulation chambers. What do you recommend for a process to clean steel piping contaminated with DC-704 and Fryquel 550 and turbomolecular vacuum pump backing piping at JSC/NAS?
A. Alconox® detergent is the right choice, but vacuum pump grease is a very heavy difficult to remove residue. We recommend using very hot (170 deg F if possible) 2% Alconox® (20 g/L) followed by a very hot first rinse…
Assistance Developing Photovoltaic Cleaning Process
Q: We are looking to hire someone to design and implement a turnkey cleaning process for our Photovoltaic manufacturing application. Do you provide this service?
A: Yes. We do this type of work often. With increased governmental commitments to support renewable energy initiatives, winners and losers in solar module fabrication will be determined more quickly and by a variety of factors. One factor will be the elimination of defects to increase yields in the manufacturing process. Critical cleaning of substrates and superstrates is an essential component in achieving an optimal solar module fabrication process which reduces the cost per watt.
