WARNING:
BE CAREFUL WHEN YOU DO WORK ON THE ENGINE PARTS AFTER THE ENGINE SHUTDOWN. USE APPLICABLE THERMAL GLOVES. THE ENGINE PARTS CAN STAY HOT FOR ONE HOUR AFTER SHUTDOWN AND CAN BURN YOU.
WARNING:
BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
CAUTION:
DO NOT USE METHANOL. IF YOU DO, THIS CAN CAUSE DAMAGE TO ENGINE TITANIUM PARTS.
CAUTION:
DO NOT WASH AN ENGINE WHICH HAS BEEN EXPOSED TO DRY CHEMICAL FIRE EXTINGUISHING AGENTS.
CAUTION:
DO NOT WASH AN ENGINE UNLESS THE EGT IS BELOW 150 DEG.F (66 DEG.C).
CAUTION:
DO NOT WASH AN ENGINE AT TEMPERATURE BELOW 14 DEG.F (-10 DEG.C).

A. Engine Washing Requirements
(1) General:
(a) You can wash the engine either with pure water only (Ref. AMM TASK 72-00-00-100-804) or with a solution of the gas path cleaner (Material No.CP5060) , only ZOK 27, R-MC G21 or Ardrox 6367 (Ref. AMM TASK 72-00-00-100-803):
1 For best results, it is recommended to do an engine gas path water wash with detergent (Ref. AMM TASK 72-00-00-100-803), heated to between 133 deg.F (56 deg.C) and 158 deg.F (70 deg.C), to do the wash of the engine gas path.
a If you do not use detergent, you can use pure water (Ref. AMM TASK 72-00-00-100-804), heated to between 133 deg.F (56 deg.C) and 158 deg.F (70 deg.C), as an alternative.
2 An engine gas path water wash using detergent (Ref. AMM TASK 72-00-00-100-803) provides the most effective method for cleaning the engine compressors.
However, the use of detergent requires the strict application of the engine rinsing and the bleed system cycling per AMM procedures to thus prevent fumes in the cabin when the aircraft resumes revenue service operation.
(b) In both cases, you can use isopropyl alcohol (Material No.CP1041) as anti-freeze agent if the air temperature is below 41 deg.F (5.00 deg.C).
(2) Water:
(a) Water properties:
1 Use water with less than 500 ppm of total dissolved solids, less than 50 ppm of the total of chlorine and chloride and a pH of 6.8-8.0.
1 Increase the temperature of the water to between 133 deg.F (56 deg.C) and 158 deg.F (70 deg.C), to wash and clean the gas path.
(3) Cleaning solution (if required):
(4) Anti-freeze mixtures:
(b) Prepare the mixtures as follows:
1 For temperatures from 41 deg.F (5.00 deg.C) to 23 deg.F (-5.00 deg.C), mix 25 percent of isopropyl alcohol (Material No.CP1041) with 75 percent of water.
2 For temperatures from 23 deg.F (-5.00 deg.C) to 14 deg.F (-10.00 deg.C), mix 35 percent of isopropyl alcohol (Material No.CP1041) with 65 percent of water.
(c) For air temperatures below 14 deg.F (-10.00 deg.C), do not clean the engine.

(2) Water:
(a) Water properties:
1 Use water with less than 500 ppm of total dissolved solids, less than 50 ppm of the total of chlorine and chloride and a pH of 6.8-8.0.
NOTE: Potable water is usually sufficient.
(b) Water flow: CAUTION:
DO NOT APPLY WATER AT MORE THAN 5 US GAL (19 LITERS) PER MINUTE. IF YOU DO, ENGINE DAMAGE CAN OCCUR.
1 A water flow between 4.5 USgal (17 l) and 5 USgal (19 l) per minute. NOTE: If the water cart does not have a flowmeter, you can calculate the flow rate using a container of a known quantity and a stop watch.
(c) Water temperature: 1 Increase the temperature of the water to between 133 deg.F (56 deg.C) and 158 deg.F (70 deg.C), to wash and clean the gas path.
(3) Cleaning solution (if required):
WARNING:
USE RUBBER GLOVES AND EYE PROTECTION WHEN HANDLING LIQUID DETERGENT. LIQUID DETERGENT AND ANTI-FREEZE SOLVENT HAVE LOW FLASHPOINTS.
KEEP AWAY FROM HEAT AND OPEN FLAME. PROVIDE ADEQUATE VENTILATION. STAND AT LEAST 3 FEET (1M) AWAY FROM COWLING INLET WHEN SPRAYING LIQUIDS INTO ENGINE TO AVOID PERSONAL INJURY.
(a) Mix 20 to 25 percent of the gas path cleaner (Material No.CP5060) only ZOK 27, R-MC G21 or Ardrox 6367, with 75 to 80 percent of water. (4) Anti-freeze mixtures:

CAUTION:
USE ONLY ISOPROPYL ALCOHOL AS AN ANTI-FREEZE MIXTURE. METHANOL CAN CAUSE CORROSION OF THE TITANIUM PARTS OF THE ENGINE.
(a) Use anti-freeze mixtures at temperatures below 41 deg.F (5.00 deg.C). (b) Prepare the mixtures as follows:
1 For temperatures from 41 deg.F (5.00 deg.C) to 23 deg.F (-5.00 deg.C), mix 25 percent of isopropyl alcohol (Material No.CP1041) with 75 percent of water.
2 For temperatures from 23 deg.F (-5.00 deg.C) to 14 deg.F (-10.00 deg.C), mix 35 percent of isopropyl alcohol (Material No.CP1041) with 65 percent of water.
(c) For air temperatures below 14 deg.F (-10.00 deg.C), do not clean the engine.
