GREEN GODDESS - Bluing Powder 500g
Natural Bluing Powder – Tired of yellow/grey tinted white sheets? Get those sheets whiter than white with this old-fashioned powder.
This Natural Bluing Powder is made out of nothing but baking soda and Prussian Blue pigment.
- highly concentrated – Use 1 tsp of bluing powder for a single sheet set, 2 tsp for double, queen or king. If sheets are really grey add 3 tsp.
- 50 teaspoons per 500g
- must be added to final rinse when the tub is full to avoid staining.
- DO NOT leave to soak, start the final rinse cycle immediately. If you soak you will get blue specks on your whites. This is NOT a soaker.
Instructions to use: Wash your sheets as normal UNTIL the final rinse. Once your machine has filled for the final rinse, add a tsp of bluing powder into your load. Start the rinse cycle immediately, DO NOT leave to soak. Once the wash cycle has completed, hang your sheets in the sunlight to dry for the final part of the process to occur.
Be sure that the tub is full before adding bluing powder so that you don’t get blue splotches, if you have a front loader dissolve the powder in a cup of water before adding. If you don’t know when the final rinse starts on your machine starts you’ll need to time it. Once you know how long it takes you can use an oven or phone timer so you know when to put the bluing powder in.
How the Bluing Powder works …
The way that the bluing process works is to swap yellow pigments for blue pigments and vice versa. When we initially make our product it is blue, over time the blue pigment grabs the yellow pigment out of the baking soda so it looks yellow. When the product is diluted in LOTS of water, the baking soda dissolves away and the powder goes back to being blue and then attaches to the yellow pigments in the sheets, which is the first stage of the whitening process.
The second stage is when the sheets are left to dry in sun light, the second part of the whitening process occurs at this stage, leaving your sheets with that nice crisp white finish.
Even if you dissolve the bluing powder in a cup of water you will not get blue water as that would then also stain your sheets, there’s only a little powder in each application as that’s all that is needed each time. When we initially make our product it is blue, over time the blue pigment grabs the yellow pigment out of the baking soda so it looks yellow. When the product is diluted in LOTS of water, the baking soda dissolves away and the powder goes back to being blue and then attaches to the yellow pigments in the sheets, which is the first stage of the whitening process.
Note to all school teachers:
The bluing powder is also perfect for school projects – we aren’t exactly sure what the schools do with it but all the teachers seem very happy!
