A washing machine has been launched for the Indian market, with a special mode to tackle curry stains.
Panasonic said the introduction of a 'curry' button followed complaints from customers struggling to fully get the food off their clothes.
It says development took two years, testing combinations of water temperature and water flow.
The machine has five other cycles aimed at the Indian consumer, including one to remove traces of hair oil.
Wringing the changes
As part of the development, Panasonic researchers analysed what went into a typical Indian household's curry dish.
The firm said it then tried to establish the optimal time and water temperature required to remove the stains.
