It is generally not recommended to wash clothes with blood stains together with white clothes in the washing machine. Blood stains can be tough to remove, and there is a risk that the stain could transfer to the white clothes, causing discoloration.
To effectively remove blood stains, it's best to treat them separately before washing the garments. Here's a general process to remove blood stains from clothes:
Act quickly: The faster you address the stain, the easier it will be to remove. Rinse the stained area with cold water as soon as possible. Avoid using hot water, as it can set the stain.
Pre-treat the stain: Apply a small amount of liquid detergent, hydrogen peroxide, or a mixture of water and salt or baking soda to the stain. Gently rub the stain with your fingers or a soft brush to work the solution into the fabric.
Soak the garment: If the stain is stubborn, you can soak the garment in cold water with an enzyme-based stain remover or a mixture of water and oxygen bleach. Make sure to follow the product instructions and the garment's care label.
Check the stain: After pre-treating and soaking, check to see if the blood stain has been removed. If there's still some residue, repeat the pre-treatment and soaking process until the stain is gone or significantly reduced.
Wash separately: Once the blood stain is gone or minimized, you can wash the garment separately in the washing machine. If the garment is white and you're concerned about any lingering traces of the blood stain, it's better to wash it with other white clothes or light-colored items.
Remember, always read and follow the care instructions on your garments' labels and any stain remover products you use. If you have any doubt about washing certain items together, it's best to err on the side of caution and wash them separately to avoid potential damage or staining.
