Cleaning Time

Are there other cleaning variables, besides increasing cleaning time, which would allow for a more thorough cleaning process?

At Alconox, Inc we recognize that “While manual cleaning may take minutes, and spray cleaning seconds: soaking may take hours, possibly overnight, to achieve comparable cleanliness.” The Aqueous Cleaning Handbook p 22-23

Yes, cleaning time can be accelerated by increasing temperature, increasing agitation and by the use of a more aggressive detergent. Of course if none of these variables can be changed, perhaps because the substrate is too delicate or the proper equipment unavailable, then be prepared for longer cleaning times. For more information see Chapter 3 of The Aqueous Cleaning Handbook.

Cleaning Olanzapine

Which detergent should be used for manual & CIP cleaning of Olanzapine?

Olanzapine has a predicted water solubility of 0.5 mg/mL making is very slightly soluble in water. There are n-heterocyclic groups which means it can be cleaned by either an acid or an alkali, possibly slightly better by an alkali. This is a medium small molecule that is slightly polar and should be emulsifiable. Use Solujet for spray CIP cleaning. Solujet can also be used for manual cleaning (operators have to wear protective gloves & eyewear when handling), although Liquinox would also work for manual cleaning.

Cleaning with Tergazyme

How long will the enzyme in a 1% solution of Tergazyme remain active?

A 1% Tergazyme solution is designed to give good reliable cleaning performance for 8 hours at 120 deg F. This is designed to correspond to an 8 hour work shift in a hospital. We are confident that after 8 hours there will still be good enzymatic activity as long as you have not exceeded 130 deg F temperatures, so if by chance the Tergazyme solution is not changed or made fresh at the beginning of a shift, it should still provide some cleaning efficiency. We do not recommend routinely using a solution for 16 hours.

Detergent 8 vs. Alconox, Powdered Precision Cleaner

What are some differences between using Alconox or using Detergent 8 to remove oily residues from aluminum?

Detergent 8 is slightly better at removing oily organic residues, natural ester oils and rosins. However, Alconox is better on particulates and inorganic residues than Detergent 8. Alconox is also effective on oily residues and will work better in hard water than Detergent 8. Use caution when cleaning aluminum. Detergent 8 has a pH of 11.5 which will attack most bare aluminum that has not been anodized or protected. Aluminum can be cleaned safely without attack in pH 9.5 Alconox, however Alconox will very slowly attack aluminum in extended contact time.

Acid vs. Alkaline cleaners

What are the differences between acid cleaners and alkaline cleaners?

Acidic cleaners are commonly used to brighten or etch metals and are effective at removing any mineral deposits or oxidation on surfaces. Generally, acidic cleaners are also ideal for removing ant starches, carbonates, and insoluble hydroxides. Since most soils are acidic, alkaline cleaners are very effective. Alkaline cleaners remove oils, fats, greases, proteins and an array of other soils. Most cleaning applications will involve an alkaline cleaner or a combination of an alkaline cleaner and an acidic cleaner. Alconox offers acidic and alkaline cleaners for pharmaceutical, medical device, manufacturing and various other industries. For information on all Alconox brands, visit
