Look at the shoes and stains. If they are water stains or coffee stains on boots, generally use a wet towel stained with white vinegar to press the stains for a few minutes and wipe them gently to remove the stains. If there are yellow stains on small white shoes, you can brush them with toothpaste. If the stains on the shoes are juice or sweat, you can also soak them in 3% salt solution for about 5 minutes.
If the shoes are expensive and the stains are difficult to clean, it is recommended to take them to a dry cleaner or shoe store to avoid damaging the shoes.
When the shoes are stained with stains, they should be cleaned as soon as possible, especially canvas. It is difficult to clean them completely after a long time. （XieShangShuaBuDiaoDeWuZiNaShenMeXi）
