EFNAL care Down Jacket Cleaner Waterless Detergent Brand new, unused. EFNAL care is based on the concept of "new habits and new common sense," and is a waterless detergent specifically for down jackets that allows you to easily clean, deodorize, and disinfect clothes that are difficult to wash, without using water. How to Care for Your Down Jacket 【Basic Care】 Directly spray on areas that come into direct contact with skin, such as the inner collar and cuffs, or on areas where dirt is a concern. Use a dry cloth to gently pat and wipe. 【For Stubborn Stains】 Leave the foam on for about 30 seconds, then use a cloth wrung out in warm water to gently pat and wipe. 【For Overall Care】 Spray the appropriate amount directly onto a dry cloth. Rub the foam into the cloth and then gently wipe. 【If Water Rings Appear】 Immediately use a cloth wrung out in warm water to gently pat and blend. Then, wipe the water ring area to disperse it.
