2.1.6.2.10 MIL-PRF-87937, Cleaning Compound Aerospace<br />
Equipment, Type III, is a gelled cleaner, and is effective for<br />
cleaning medium to heavily soiled surfaces. May be used on<br />
painted or unpainted surfaces where additional dwell time is<br />
desired. It should be used in areas that can tolerate high volumes<br />
water rinsing necessary to remove the gelled cleaning<br />
compound. Since the cleaning compound is a gel, it will<br />
adhere to vertical surfaces for more effective cleaning. To<br />
ensure the cleaning compound effectiveness, apply the cleaning<br />
compound to dry surfaces. Type III will separate-out oily<br />
waste, however, because the cleaning compound is a gel-type<br />
material the oil/cleaner separation is difficult to determine<br />
unless the solution sits for several hours.<br />
2.1.6.2.11 MIL-PRF-87937, Cleaning Compound Aerospace<br />
Equipment, Type IV, is heavy duty cleaner, effective for cleaning<br />
heavy oils and greases. This material differs from Type I in<br />
that it has no flash point. Suitable for use on high gloss or<br />
tactical paint systems. Type IV will separate out oily waste, so<br />
the oil can be removed and disposed of while the remainder is<br />
sent to a waste treatment facility.<br />
2.1.6.2.12 MIL-PRF-87937, Cleaning Compound Aerospace<br />
Equipment, Types I and IV cleaners may be used in dip tanks<br />
but are not formulated for use in vapor degreasing tanks. The<br />
gel-type cleaning compounds are not suitable for dip tank<br />
cleaning operations.<br />

Allow the cleaner to dwell<br />
for 1-2 minutes, then agitate<br />
with a brush and completely<br />
rinse with water and allow<br />
drying.<br />
The gel-type cleaning compound<br />
is designed to adhere to<br />
vertical surfaces for more<br />
effective cleaning. The cleaning<br />
compound contains abrasives<br />
that remove soils by<br />
wearing away the surface that<br />
holds the soil. This cleaner<br />
will raise the gloss of gloss,<br />
semi-gloss, or flat topcoats.<br />
The cleaning compound<br />
should be used in areas that<br />
can tolerate high volumes<br />
water rinsing necessary to<br />
remove the gelled cleaning<br />
compound. Do not use on<br />
plastic parts.<br />
