These are two examples of Reckitt’s Bag Blue laundry blue bags made in Australia by Reckitt and Colman (Australia) Ltd in about the 1930s and 1940s. The blueing process was used to whiten material made yellow from soap and age. After washing, a ‘blue bag’ was dipped in a clean tub of cold water. Each piece of clothing was turned inside out and plunged into the water, then rinsed. ‘Blue bags’ were also handy as a remedy for bee stings.
Two cylindrical blocks of laundry blue, wrapped in a cream paper with red stripes. Text across the paper wrapping reads 'Reckitt's Bag Blue / Remove label wrap block in flannel / and stir in the last rinse'.
The laundry blue was stirred into the final rinse when washing cloths to whiten the clothing.
