My favorite sheet laundry product. I’ve been using this for years to wash my bedding. I don’t know what their formulation is but my sheets always come out looking fantastic. Gentle and powerful at the same time. Nice lovely scent without being over powered. Makes you want to cuddle in bed when you awake in the AM. I also use their fragrance liquid in lieu of softener and their drying sachets in the dryer if I’m having house guests. They can’t figure out why they slept so well ......lavender is my fragrance of choice! For very special occasion I’ve also used the Le Blanc Lavender Spray for ironing the pillow cases and sheets. I’ve also use the spray to freshen up the actual pillows.
