- Undo all the buttons and turn your shirt inside out.
- Wet the shirt first in warm water and washing powder and add a dash of whitener / delicate bleach.

- Soak for a few minutes in the powder / bleach solution and then wash as usual in the machine, again, using washing powder and now fabric softener.
