While I was writing the new book I remembered the terrible days when I ruined three sets of beautiful white sheets trying to recreate Bluo from my nana’s day. The idea behind bluing is that the blue pigment exchanges with the yellow or grey pigment which makes white sheets look dull after lots of washes. I believe that the optical brighteners and other chemicals left in sheets when using supermarket laundry powders adds to this dullness.
So I bought some Prussian Blue pigment from the local art supply shop and set about mixing it with baking soda. It took a while to get the dose quite right – which didn’t happen until I had streaked all my sheets bright blue!
Bluing powder is so easy to make and I would recommend you use it within a few months. Add to the rinse cycle only when the bowl is full or you may get streaks.
Mix three cups of Green Goddess Premium Baking Soda with 1/2 tsp of Prussian blue pigment powder (available at art stores). Use 1 tsp of this mix in your final rinse, making sure the bowl is full before adding (you may have to time this after the wash cycle). Do not soak, tub must agitate to disperse the powder.
For best results dry in direct sunlight t activate the particles. Wendyl.
