Try salt. It has strong dehydrating properties, which means it can absorb water and blood and act as a super stain remover. You just need to make a paste of salt and cold water and apply it on the period-stained area.
I've had good luck by soaking my sheets (the affected portion) in white vinegar for ~30-60 minutes. Then rub the stain with your fingers, or if it's really bad, scrub the fabric against itself, as you rinse it in cool water. You might have to repeat this if the stain is somewhat better but still obvious.
Blot (don't rub) the stain with your cloth or paper towel until you've removed as much blood a possible. Mix a solution of one part vinegar to two parts cold water. Dip a clean cloth or paper towel into the solution and dab at the stain. Again, be sure not to rub or scrub!
Mix baking soda and some cold water to make a paste, apply to the stain and let it sit for 30 minutes. Remove with a damp cloth. Mix some baking soda and hydrogen peroxide and apply the mixture onto the stain. Let it sit, then clean it off with a damp cloth.
Leave baking powder on the stain for 30 minutes, then shake it off. Leave cornstarch on the stain for 10 minutes, then shake it off. Press the baby powder into the stain and leave it there overnight. Shake it off the next morning.
You can try pouring white vinegar on the blood stain and let it sit for a few minutes. After, gently dab the area with a paper towel or wet rag. If the stain is still visible, repeat the process again and let it work its magic!
Use a concentrated dish soap, such as Dawn, and apply it to the stain to loosen the fibers. Soak period underwear in cold water with gentle detergent for 10-15 minutes to help release stains.
Mix two parts lemon juice, one part baking soda, and blot it onto the bloodstain. Let it sit for five minutes and then remove it with a sponge or by rinsing. Repeat as many times as necessary. The carbonation and phosphoric acid in Coke can work wonders on bloodstains.
Make a paste of baking soda and cold water, then apply it to the stain. Allow the paste to sit for 30 minutes, then gently scrape it off with a soft brush or cloth. Soak a clean cloth in white vinegar and dab the stain to remove any remaining residue.
This stony silence might be because these fine lodgings don't want to be associated with gross bodily activities or because they're collectively covering up a not-so-dirty secret: On the whole, most hotels don't seem to charge guests for stained beds. If they do, it's on a case-by-case basis.
Cold water is necessary here as it prevents clotting and causes the setting of blood into the fabric. Once it dries and clots, it's very difficult to remove from the sheet. Prefers a pre-soak with an enzyme-based cleaner that breaks down proteins in the blood, commonly used by hospitals.
You can make a paste from cold water and baking soda (yes, the kind you put in your fridge or freezer to deodorize it). Apply the paste to the stained area and work it gently in with a toothbrush. Rinse and repeat until the stain is gone.
Generally, a stain less than two months old can be treated; a stain one-day-old is easier than one that is two-weeks old, etc. Perhaps the most distressing example of ageing is coffee: so easy to remove but permanent if left untreated!
Unfortunately, sometimes blood stains happen when you're out of the house, and at that point, soap and laundry products won't do you any good. Luckily, salt water or saline can come in handy in a pinch. Plain old table salt and cold water do really well for getting period blood out of clothes after the stain has dried.
Sponge the stain with hydrogen peroxide or rub bar soap into the stain and scrub by hand in cold water. Apply laundry pre-treater or rub in liquid laundry detergent, and wash the remaining stain in warm water with a fabric-safe bleach until the stain is gone.
Are old blood stains permanent? Old blood stains can be especially difficult to remove, however it's not always impossible. If the blood stains have been washed in hot water or put through the dryer, this could have set the stain and made them permanent. But, it's still worth giving the above steps a try.
The Culprits Behind Yellowing Sheets
Believe it or not, the main culprit behind yellowing white sheets is… well, us! Our bodies produce oils and sweat and shed dead skin cells, which all find their way into the fabric of our sheets.
Bleach plays a significant role in maintaining the bright white colour of hotel sheets. Hotels often use a diluted solution of bleach in the washing process to remove any lingering stains and to disinfect the fabric.
