Lexan Cleaner (AFCO 5308) is a low-foaming, alkaline liquid detergent designed for cleaning "LEXAN" or polycarbonate water bottles without causing the plastic to become opaque or cloudy. AFCO 5308 will effectively clean lightly soiled polycarbonate containers but is not recommended for heavily soiled bottles which requires a soaker-washer type operation. For soaker-washer type applications, Super Alk HD (AFCO 5237) is recommended.
