My white clothes are very bright like snow. I clean things fast my husband calls me the Snow Queen

200 grams of laundry detergent
10 liters of water
a few small pieces of potassium permanganate
Use.
Put around 200 grams of laundry detergent into a bucket of warm water.
Mix a little potassium permanganate in a glass of water. The water should have a light pink color.
Mix until the small pieces disappear completely. Do not put potassium permanganate directly into the bucket to avoid getting stains on clothes from undissolved crystals. Pour the potassium permanganate from the container into a bucket.
Put clean white clothes in the bucket.
Put plastic tightly over the bucket and wait for the water to cool down completely. Next, wash the clothes well with water.
