Most housewives are used to wash all clothes in a washing machine.
They don't even look at labels. In the end of washing your favourite jeans or dress become smaller and you can't wear it.
Some clothes are not destined for the washing machine. Never wash the following clothes in the washing machine.
Underwear
Wash underwear and swimsuits by hands so you don't damage the fabric of these clothes.
If you wash underwear and swimsuits in the washing machine your clothes would loose their shape. Some underwear is decorated with beautiful laces which can be damaged in the washing machine.
Clothes with wool
If you wash clothes with pets' wool in the machine they wouldn't contain less wool after washing.
Your clothes will look sloppy.
Caps
Don't wash clothes with a frame in the machine. Wash them by hands and don't press, otherwise you loose your favourite cap or hat.
Clothes with petrol spots
You should not wash clothes with petrol spots of other flammable liquids in the machine.
Wash such clothes by hands to avoid other clothes getting dirt.
