Text: Billeted with HUDSON'S
TOMMY is the first to appreciate a clean Billet, and the first to lend a hand to keep the Billet clean. He is, you may be sure, QUITE AT HOME with Hudson's Soap. The good old soap is always of Uniform quality, so Tommy is perfectly equipped with it.
A clean sweet-smelling wholesome soap. Hudson's ensures cleanliness with typical British Thoroughness. Tommy and Hudson's will be busy this spring.
SPLENDID FOR WASHING UP AFTER MEALS.
IN PACKETS EVERYWHERE.
[I don't know whether Hudson's soap was specifically for washing up, or whether it was also intended for washing people (a 'toilet' soap). Hudson's also made Rinso for washing clothes (see below), so presumably the soap advertised here was not intended for clothes washing - but the range of specialised cleaning products that we have now did not exist in 1915.]
From the Halifax Courier, 13th March 1915.
Text: Every housewife should seriously consider the saving in coal effected by the use of RINSO.
RINSO washes in cold water equally as well as less scientific preparations do in hot. Thus the cost of maintaining the copper fire is avoided -- an overheated and unwholesome atmosphere is dispensed with. Labour is saved, too, because you soak the clothes in RINSO and cold water overnight -- leave them soaking all the night -- Rinse and hang to dry in the morning.
RINSO is the easy washer -- easy for the housewife -- easy for the wash.
[The copper fire was the fire under the copper, the tub for washing clothes. Many households would only have one stove, for cooking, and the water for washing clothes would be heated there in pans, and transferred to the washing tub, but larger houses might have a separate laundry room. Our house, for instance, (built about 1906) had a built-in copper in the basement, with its own chimney.]
