We should be washing jeans only once a month, jumpers once a fortnight and pyjamas once a week.
But underwear and gym clothes should still be washed after every wear, a Society of Chemical Industry report says.
It points out that washing clothes has a “huge environmental impact”.
And it says cleaning less often makes clothes last longer, recommending washing tops only every five wears, bras once a week and dresses every four to six wears.
Experts also say we should hand wash our undies.
Bizarre alternatives suggested for cleaning clothes include freezing jeans and steaming your knitwear.
