It is not very difficult to wash some inconspicuous oil stains on clothes. The washing machine can also clean them, but the prerequisite is to choose the appropriate laundry detergent first.
Just like myself, I usually throw it directly into the drum washing machine, and then use Liby's low-foaming machine washing detergent. I bought this after being introduced by a supermarket shopping guide. The shopping guide also explained the principle of stain removal, which roughly means that there are some active agents in it that can quickly decompose and remove oil stains while preventing dirt from accumulating again. Moreover, this product does not have much foam and is easy to use. Rinse and quick wash modes can also clean clothes.
