b.
For components, the following steps should be followed:
WARNING
The TSP cleaning solution is harmful to eyes and skin. Wear
chemical protective apron, gloves, and goggles/face shield when
handling or working with the solution.
(1)
Prepare a solution consisting of 2 lb (0.9 kg) TSP, 0.5 oz (14.7 ml) nonionic detergent and 80 gallons
(302.8 I) of distilled or deionized water.
(2)
Heat solution to 165°F (74°C), mixing occasionally during the heating.
(3)
Disassemble components down to the smallest parts (separate and clean soft goods and aluminum
parts as specified in paragraph 4-36) and soak in the solution for 10 minutes minimum, 30 minutes
maximum.
(4)
After soaking, clean the parts in the ultrasonic cleaner until all visible traces of contaminate dirt or
grease are gone.
(5)
For components too large for an ultrasonic cleaner, scrub the parts with a nylon bristle brush until all
visible traces of contaminate dirt or grease are gone.
(6)
Rinse all parts in running hot distilled water or deionized water until all visual traces of cleaning solution
are removed.
(7)
Draw 10 ml sample. Agitate water to observe for soap bubbles. If any soap bubbles are present, repeat
steps (6) and (7) until no bubbles are observed.
(8)
Blow dry components with clean air, nitrogen, or helium.
(9)
Reassemble components using an approved lubricant.
(I0)
Bag and sea[ or tape closed all components and ends of pipe or hoses with plastic until ready for
reinstallation.
c.
For cleaning pipe or tubing, the following procedures should be followed:
(1) Determine the volume of cleaning solution by estimating the length of pipe or hose to be cleaned
and the size of the pipe to be cleaned. Look up the appropriate pipe/tube size and then the corresponding
volume per one foot length in table 4-3. Multiply that volume by the estimated length to be cleaned. After the
total volume is calculated, multiply the answer in cubic inches by 0.0433 to obtain the number of gallons to fill
the system. Determine applicable flow rate from table 4-4 and multiply flow rate by thirty (30) to compute
number of gallons required to pump through the system. Add volume required to fill system and the volume
required to pump through the system for the total volume of cleaning solution required.
