How to whiten white clothes and remove old yellowish stains

Finally, wash the garment normally and enjoy the results: it will be very white and without any yellowish stains.

Apply heat
A trick as simple in its application as it is little known, for which you will only need an iron and talcum powder.

Sprinkle talcum powder on the yellowish areas of the garment, then hold the hot iron close to the garment for a few seconds, without resting it. The idea is to get the heat of the iron, but without letting it come into contact with the garment.

After applying heat, pass the iron over the stain. Just leave it for 2 or 3 seconds to whiten the garment. Finally, shake the garment to remove the talcum powder.
