Bloodstain Removal Caution!
Bloodstains tend to coagulate and bind tenaciously, thus using an appropriate tool like a bamboo skewer helps to dislodge the stain.
Caution! In most cases, the finishes are likely removed, then refinishing with coloring the topcoat has to factor into consideration.
What is Blood Stain?
A blood stain is a protein-based stain that has the tendency to coagulate with the leather protein fiber and makes removal tougher than other protein stains even working with appropriate leather protein stain removal.
It has also an iron component that will get darker in color when it ages.
Dried blood stains will range from tan to black with an outer ring.
When the protein component is first removed with Protein Cleaner-9.9 and rinsed with Acidifier-2.0 neutralizing effect, the other secondary iron component present will need to go through another reduction-oxidation (redox) chemical reaction again when dry and neutralized with Basifier-8.8.
Thereafter, another option available is leather conditioning to revive color intensity or color refinishing to camouflage remaining residue from compounded and failed attempt stains.
Hydrogen Peroxide, an example is not recommended for bloodstain removal on leather, as oxidation will “cook” the protein leather fiber and the bloodstain as well, altering their original chemistry, thus remaining stains may not match up with the chemistry of the mentioned products formulated for.
