Washing a shirt

Washing the white and blue shirt

Turn the shirt inside out
Preferably wash it by hand in a lukewarm warm soapy water with little detergent. Then prod it and hang up as wet as possible
Machine wash at 30 degrees
Program: delicates, wool or shirts
Use very little detergent
Centrifuge revs 600 or less
Remove immediately from the machine after washing
Just as well prod your shirt
Hang up on a hanger and tighten
Moist ironing

Coat the inside of the collar and cuffs from day one with a remover, soft soap or soda ash. This way you keep your shirt white and clean the longest.
Wash your white shirt with white laundry only. (no light colors)
Wash your blue shirt only with light colors (no dark colors).
Do not use synthetic deodorants. It prevents discoloration of the armpits of your white shirt.
Always let your deodorant dry before you put on a shirt
Hanging your black shirt outside for a night, saves a wash.
