Milky white laundry: all you need is this ingredient.

Another tip: Avoid applying perfume or deodorant directly to clothing. These can cause stains to turn yellow over time.
Furthermore, drying in direct, strong sunlight can cause yellowish white. But even then, there’s a solution.
The secret ingredient for brilliant white laundry.
The solution may already be in your medicine cabinet: aspirin.
Aspirin contains acetylsalicylic acid, which has cleansing properties—even when the tablets have expired and can no longer be taken.
So, if you want to remove stubborn stains and thoroughly clean your clothes, aspirin is an environmentally friendly alternative.
How to use aspirin to brighten:
Fill a bowl with hot water.
Add 5 aspirin tablets (325 mg each).
Let them dissolve completely.
Place the clothes in the water and let them soak for about 8 hours.
Then rinse and machine wash as usual.
Quicker option:
Simply add 5 aspirin tablets directly to your regular laundry. The result is a little less intense, but still visible.
With this simple trick, you can make your whites shine again, without harsh chemicals.
