Yes! And here¬*is some more info on cold cleaners.
4.6 Solvent Degreasing
Solvent degreasing (or solvent cleaning) is the physical process of using organic solvents to
remove grease, fats, oils, wax or soil from various metal, glass, or plastic items. The types of
equipment used in this method are categorized as cold cleaners, open top vapor degreasers, or
conveyorized degreasers. Nonaqueous solvents such as petroleum distillates, chlorinated hydrocarbons,
ketones, and alcohols are used. Solvent selection is based on the solubility of the substance to be
removed and on the toxicity, flammability, flash point, evaporation rate, boiling point, cost, and
several other properties of the solvent.
The metalworking industries are the major users of solvent degreasing, i. e., automotive,
electronics, plumbing, aircraft, refrigeration, and business machine industries. Solvent cleaning is also
used in industries such as printing, chemicals, plastics, rubber, textiles, glass, paper, and electric
power. Most repair stations for transportation vehicles and electric tools use solvent cleaning at least
part of the time. Many industries use water-based alkaline wash systems for degreasing, and since
these systems emit no solvent vapors to the atmosphere, they are not included in this discussion.
188.8.131.52 Cold Cleaners -
The 2 basic types of cold cleaners are maintenance and manufacturing. Cold cleaners are
batch loaded, nonboiling solvent degreasers, usually providing the simplest and least expensive method
of metal cleaning. Maintenance cold cleaners are smaller, more numerous, and generally use
petroleum solvents as mineral spirits (petroleum distillates and Stoddard solvents). Manufacturing cold
cleaners use a wide variety of solvents, which perform more specialized and higher quality cleaning
with about twice the average emission rate of maintenance cold cleaners. Some cold cleaners can
serve both purposes.
Cold cleaner operations include spraying, brushing, flushing, and immersion. In a typical
maintenance cleaner (Figure 4.6-1), dirty parts are cleaned manually by spraying and then soaking in (...).

Product Data Sheet
ISO-Cold Cleaner HP 89/5 and HP 90/1
ISO-Cold Cleaner are halogen-free, water clear solvents for technical cleaning purposes. These products
show good solving properties towards greases and oils. The evaporation of ISO-Cold cleaner HP 90/1 is
comparable with those of solvents like methylene chloride or trichloroethylene.
In contrast to halogenated solvents the products are biodegradable and practical non-toxic.
Type HP 89/5 und HP 90/1 are different in polarity and therefore in their capability to dissolve impurities.
The right cold cleaner can be found by pilot tests.
ISO-Cold Cleaner clean grease and oil polluted metal, plastic and ceramic parts. The cleaner are applied
undiluted by dipping, spraying or wiping with a cloth.
