Stergene — science in cleaning, from Wandsworth Common
"…for the Heavy Wash. There are some who use Stergene regularly for their dainty things, but have not yet attempted to use it for the heavy weekly laundry. And yet Stergene is quite as efficient at cleansing the dirtiest overalls as it is safe for delicate fabrics — and for the same reason. That is, Stergene — the new scientific cleanser and grease remover — is soapless; it can not form unpleasant soap scum (much of which remains in clothes washed with old-fashioned soap). That is why Stergene keeps colours fresh and bright, silks silky, woollens soft and fleecy. So remember: Stergene washes everything."
[Stergene Ltd., whose address appears at the foot of the advertisement as Wandsworth Common, London (telephone: Balham), was the sister brand to Domestos — both products of the same company, which had offices at 18–18a Bellevue Road, Wandsworth Common, S.W.17.]
