Even the most fastidious housewife has encountered yellow stains on pillowcases or sheets at least once. Dealing with them can be very difficult.
Simple washing usually doesn't help here.
You can use bleach or stain remover.
But there are a few life hacks that will help you clean things.
For example, you can apply laundry soap to the stains and leave the laundry to soak for a day, then leave the sheets in the soap solution and wash them in the traditional way.
Some housewives soak pillowcases in a solution of soda and salt (4 tablespoons of bulk product per liter of water) for several hours, and then throw the items into the machine.
Some people prefer to use starch or baking powder. 1-2 spoons are enough for 5 liters of water for soaking laundry.
You can remove yellow stains using a small amount of ammonia in a basin of hot water.
