I cooked the leftovers with water and salt out the soaps to mix with washing soda. The main purpose is to recycle soap leftovers, no need to measure the materials precisely. 【配方/Recipe】 皂屑/soap: 1kg 碳酸鈉/sodium carbonate: 1kg 過碳酸鈉/sodium percarbonate: 1kg 水/water: 很多/a lot 鹽/salt: 適量/moderate ------------------------------------------------------------- 訂閱頻道/Subscribe👉https://goo.gl/chz3Dp 粉絲專頁/Facebook👉https://www.facebook.com/ohmycattles/ 聯絡信箱/E-mail👉liao.yvonne@gmail.com
