1. Apply a proper amount of laundry detergent to the stain, let it stand for 10 ~ 15 minutes, and then use a small brush for routine cleaning.
When you touch the sauce, immediately take it to the bottom of the faucet and wash it with cold water. When washing, put the stained side down and let the water directly wash away some residual stains. Then apply white vinegar on the front and back of the whole stain and clean it with water. If there are traces left, you can wash them with soap again and repeat the above steps until they are clean.
3. Mix baking soda powder and laundry detergent in half, and add water to make a paste. Wipe the prepared baking soda on the stain, dry the baking soda, brush it off with a small brush, and then wash it with warm water.
I hope my answer can help you.
