How to remove a dried, old and encrusted blood stain on fabric, a sheet, a sweater, jeans or other clothing. Old, dry blood stains, over time or after washing, turn into brown stains that are difficult to remove.
Recovering blood-stained sheets
Baking soda is an eco-friendly cleaning product that can also clean a blood stain on a sheet. To do this, dilute one part baking soda in two parts water. Place the solution on the stain, wait thirty minutes and rub gently. Then place your sheet in the washing machine.
If you don’t have bicarbonate, hydrogen peroxide is a good alternative. To remove the blood stain, rinse it immediately with cold water then apply the product directly on it. Repeat until the stain fades and finish by cleaning with cold water. If the textile is fragile, dilute the hydrogen peroxide first.
