All promise a washing machine "whiter" than ... white! But that really keep their promise, on the basis of faked tests? So I use sodium percarbonate, this almost super green product is effective. The small dose inhaler (out of the can) allows use of the required amount. Farewell bleach which is a disaster for the environment and use the machine, while irreversible stains if handled badly! Very good seller, competitive price checked at the time of this purchase and super fast.
