Nuclear Cleaning with Alconox, Powdered Precision Cleaner

Does Alconox decontaminate stainless steel from radioactive contamination?

Answer:Yes, Alconox powder can decontaminate stainless steel of radioactive contamination. The phosphates and chelating agents combined with the wetting agents in Alconox are known to be effective at decontamination. We recommend use of a warm (if practical, otherwise ambient temperature solutions, it just takes longer) 1% (10 g/L or 1.25 oz/gal) solution of Alconox detergent in water for manual or soak cleaning. Do not use any kind of pressure spray or automated cleaning equipment as Alconox is a high foamer. Note that Alconox will bind with radioisotopes and will inhibit separation and waste treatment of the spent cleaning solutions by ion exchange columns. It is better to treat spent cleaning solutions by evaporation than by ion exchange. Sometimes it is necessary to use an anti-foamer in the evaporator depending on the evaporator design and the volume of solution being treated with what other types of waste streams if any.

Oil Cleaning with Liquinox

Does Liquinox have the same oil removing power of Dawn detergent? Will Liquinox remove glycol ether residue?

Yes, Liquinox and Dawn contain a blend of nonionic and anionic surfactants. Certain oils are best cleaned by detergents that have mixed micelles of anionic and nonionic surfactants. Using Liquinox in sonication will produce results similar to that of Dawn for oil removal. Liquinox should certainly be able to remove glycol ether residues. Be sure to rinse thoroughly to remove the Liquinox and all other residues.

How to Use and Restore a pail of solidified Alconox Powdered Precision Cleaner

Is there any way to restore a pail of Alconox to its original form after it has become solid like a rock?

Regretfully, once solidified, the phosphates in Alconox have been hydrolyzed by exposure to water or humidity and then have re-condensed and hydrated to form a phosphate cement. It is certainly possible to scrape and pound to break it up in to chunks and release powder and use these chunks for general purpose cleaning. It is not recommended to use the chunks for critical cleaning. Once the phosphates have hydrolyzed, they are chemically different than the original chemical and will not perform all of the dispersing, chelating and sequestering functions as well as the original formula did. Certainly the hydrolyzed phosphates still have significant detergency, but for the most critical cleaning, do not use the solidified and scraped Alconox.

Alconox should be stored is a closed container in a cool dry place (60 - 90 deg F). Alconox is actually fairly robust and can tolerate a fair amount of excess humidity and moisture, although eventually it will harden.

Removal of Tannin from Stainless Steel Equipment

Which Alconox detergent will clean the red staining of wine (tannin) from stainless steel equipment?

The best way to remove tannin is to oxidize it with bleach or an oxidizing agent. There are three Alconox brands that could effectively remove tannin including Detojet, which contains sodium hypochlorite bleach, Alcojet which contains an active chlorine compound that releases hypochlorite when dissovled in water, and Tergajet which contains active oxygen compound that releases peroxide when dissolved in water.
