My white pillow was definitely pure white at first, but at some point, it turned yellow. Especially since pillows used every day are prone to discoloration due to sweat or everyday stains, simply washing them isn't always enough. I wash my yellowed white pillows using sodium percarbonate. I washed it as shown in the video, and when I compared the before and after, I could definitely see the difference. However, the method may vary depending on the pillow material and whether it is washable, so please be sure to check the label before washing! If you save this, you can refer to it immediately the next time you wash your pillow. #PillowWashing #흰베개세탁 #세탁꿀팁 #살림꿀팁 #살림팁 #아이유베개 #아이유베개세탁
