Here's the cleaning process for ESAPI plates according to the TM 10-8470-207-10
a. Remove loose dirt and
lint from the outer
surface of the ESAPI
using a cloth or soft
bristle brush. Never
use a stiff bristle brush.
b. Wet the ESAPI in a
sink or shower using
warm, not hot, water.
c. Apply a mild soap or
detergent to the soiled
areas and scrub with a
cloth or soft bristle
brush. Scrub only long
enough to remove soil.
d. Heavy grease/oil
stains may be pre-
spotted with a
detergent mixture and
scrubbed with a soft
brush.
e. Rinse the ESAPI with
warm water until all
suds are completely
gone.
f. Let the plate dry by
itself, away from heat
or open flame.
I would honestly just use a soft bristle brush and lightly dampen the bristles with cold water. Don't soak the plates, and scrub gently to loosen up that dirt. Let it air dry. The TM says don't put them in the washer or dryer FOR A REASON. Because some idiot tried to hit the easy button and likely destroyed the plates and a dryer
Here's the formal inspection per TM:
The ESAPI/ESBI insert must be
turned in if any of the following conditions are present:
Outer Cover is damaged exposing the ceramic tile material.
Plate is cracked and you hear loose
pieces rattling around when shaken.
Creaking or squeaking of ceramic tile
heard when plate twisted by hand.
Composite backing is delaminating (backing material plies are separating). this can be remedied with super glue if a MINOR separation is occurring
Cracking of the ceramic tile is felt or
heard as you firmly pinch the outer ½-inch
perimeter of the plate.
Plate has been hit by a bullet or fragment.
