The water repellent finish has the advantage of repelling water like a ball.
We recommend using a neutral detergent for washing.However, if the fabric is used more frequently, a few stains will become more noticeable. We recommend that you wash the stained area carefully by hand.
Drip undiluted solution onto the stained area and wash it. If it is still difficult to remove the stain, try washing it with kitchen detergent as well. (Neutral detergent only.) It will probably make the stain much lighter.
After washing, please be sure to stretch out the wrinkles and hang it to dry. If the garment is dried with wrinkles remaining, it will be difficult to iron them out afterwards. Thin fabrics will dry in a few hours, but if possible, iron the fabric in a semi-dry state to restore the water-repellent finish and make it look nice and crisp. Please give it a try.
