(2) Clean acrylic parts (interior surface of windshield which is to be sealed) with aliphatic naphtha or
Isoproply alcohol.
Note: If sealant is to be applied, acrylic surfaces must be completely dry, without con-
taminants, prior to sealing.
(a) Fold clean lint-free cloths in such a manner as to eliminate raw edges to reduce the possi-
bility of lint contaminating the surface to be cleaned.
WARNING:
Cleaning solvents are toxic and flammable. Skin protection and eye
protection are required. Additionally, adequate ventilation and/or fresh
air masks shall be used in all closed areas.
(b) Dampen one cloth with cleaning solvent from polyethylene squirt bottle. The cloth should
not be saturated to a point where solvent drips.
Note: Never pour or spray cleaning solvent on aircraft structure because it will run back
between structural layers, then run back out again after the cleaning operations
are completed, bringing contamination to surfaces previously cleaned.
(c) Thoroughly clean small areas at a time. Wipe area dry with a clean, dry, lint-free cloth. Do
not allow solvent to air dry as a residue will remain on the surface, contaminating a follow-
ing process.
Note: If sealant is to be applied, always clean an area wider than the width of
finally applied sealant.
CAUTION: After thoroughly cleaning surfaces to be sealed, personnel should wear
clean white gloves to prevent contaminating the surfaces to be sealed. If
contamination occurs, surfaces shall be recleaned.
(d) Continue cleaning until no discoloration is evident on the drying cloth.
