The invention provides a down feather APEO (alkylphenol ethoxylates) removal method which comprises the following steps: putting down feather to be treated into a washing machine, adding water and a down feather APEO remover, cleaning and centrifugally spin-drying. The down feather APEO removing agent is prepared from the following components in parts by mass: 30 to 40 parts of polyoxyethylene lauryl ether, 12 to 18 parts of polyoxyethylene abietate, 8 to 14 parts of iso-tridecanol polyoxyethylene ether, 1.6 to 2.4 parts of dodecyl glucosamide, 2 to 7 parts of isopropanol, 0.15 to 0.25 part of polyvinylpyrrolidone, 0.03 to 0.11 part of hydroxymethyl cellulose, 22 to 32 parts of magnesium chloride, 3.0 to 5.5 parts of cyclodextrin and 80 to 112 parts of deionized water. According to the down feather APEO removal scheme, APEO in the down feather can be effectively removed, the down feather with the APEO content exceeding the standard is treated to be 50 ppm or below, and meanwhile the original performance index
