Do not wash garments/sheets in the washing machine or in hot water before the stain has been treated. This is because the protein in the blood hardens/coagulates from heat and then the stain is basically impossible to remove.
If you do not have the opportunity to clean at once, it is fine to let the stain dry until you can deal with the stain later before the washing machine.
🩸 Let the stain dry or remove it immediately
🩸 Rinse & rub the stain in ice-cold water. Then let it sit and soak for a while in the cold water for about 5 minutes. A little more time and work is usually required for a dried-out stain. Squeeze out of the water.
🩸 Bile soap - liquid or solid. Rub thoroughly into the stain. If it's on, for example, a sheet, make sure that the stain from both sides gets bile soap on it.
Done! Now it's just into the washing machine and the stain won't be found - because it's gone!
I always follow this formula myself because I know it works & it goes fast!
