Instructions:

First, take a large pot and fill it with hot water until about two-thirds of its capacity. Place the pot on the stove and put all the dirty rags inside. Then, pour a cup of vinegar, some dishwashing detergent and a cup of baking soda into the pot. Boil everything for about 5-8 minutes. Don’t forget to constantly stir the rags and then pour the water. When they cool down a bit in the sink, rub them well against each other. Finally, put them all in the washing machine and select the appropriate program. After this wash, the rags will have a second life. All the stains will disappear and you can use them again without any problems.
