COMPRESSOR CLEANER
1 Description
Ardrox
®
6367 is a liquid product formulated to clean the compressor sections of gas turbine
engines. It is solvent free and removes atmospheric soils, oils, carbon and salt deposits
during “in-situ” hot-fired and cold motor washes.
Ardrox
®
6367 is safe on all aircraft metals, plastics, windows, etc., and is non-flammable and
biodegradable. In addition, it contains an inhibitor which protects the engine components from
oxidation and corrosion for up to 3 days.
Regular cleaning with Ardrox
®
6367 helps maintain peak engine efficiency and reduces
maintenance and fuel cost. Ardrox
®
6367 is compatible with recognized antifreeze materials
used during cold weather cleaning.
2 Physical and chemical properties
These are typical values only and do not constitute a specification.
3 Method of use
Ardrox
®
6367 is diluted with demineralised water in the proportions of 1 part Ardrox
®
6367 to
4 parts water. Cleaning is most efficient, if the product is applied while the compressor is
running (cleaning mode). Pressure and flow will be dependent upon engine type and level of
fouling. Always apply Ardrox
®
6367 according to the procedures given by the engine
manufacturer.
Ardrox
®
6367 is also excellent for use in an immersion bath.

After completion of the wash, the engine should be rinsed with demineralized water and then
protected with water-displacing fluid, e.g. Ardrox
®
3-series, unless the engine is to be used
immediately. If there is no requirement to rinse, corrosion protection is assured for up to 3
days.
4 Effects on material
When used as recommended, Ardrox
®
6367 is non-corrosive to the metal alloys and paint
schemes normally used; the pH-value is neutral.
5 Shelf life, storage and disposal

Method of Control
Required chemicals
Indicator solution: Bromophenol blue
Testing solution: 0.1N Sulfuric acid
Measure
Restore the volume of the tank to its original level, if necessary, by adding water. Thoroughly
mix and take a sample of 50-100 ml.
After allowing to cool to ambient pipette 20 ml of this solution into an Erlenmeyer flask, add
about 50 ml distilled water and 5-10 drops of a Bromophenol blue indicator solution.
Titrate against 0.1N Sulfuric acid solution to a color change at pH of 4.0 from blue to yellow.
Alternatively, the endpoint of the titration could be terminated by pH indication, too.
Record the volume used as (V) ml, then the bath strength is calculated as follows:
Strength (% Ardrox
®
6367) = 1.1 * V
Replenishment of the bath
For each percentage point that the strength is low, add 1.0 liter of Ardrox
®
6367 for each
100 liter of bath solution.
Remark
The color / endpoint indication of the indicator could be trained by using both methods, pH
indication and indicator, simultaneously.
