When a protein is surrounded by water: 1  Hydrophobic amino acids will move away from the water and bury themselves in the center of the protein. 2  Hydrophilic amino acids will interact with the water molecules, and thus tend to be located on the outer surface of the protein.
The more you rub, the lighter the stain will become and it will lessen the overall drying time. Place the object in the position you want it to dry. Place the object where it will not rest against or touch anything else that could cause the stain to rub off even more. Wait 15 minutes. Look for drips and runs that may have appeared from places where the stain pooled up inside knots, cuts or edges in the wood.
Tips for Treating a Dry Blood Stain: 1  As a first option, soak in cold water overnight then move on to other options. 2  Before treating, don't leave a clean section of clothing under the stain. 3  Move it out from under the stain or when you treat the stain it could transfer to a clean area of clothing. If the blood stain is larger, lay a towel under the stained area then soak with white vinegar and let sit for 30 minutes. 2  Repeat if necessary until the stain is removed. 3  Wash as usual but don't put in the dryer until you are positive the stain is gone.
